The Professor missing episodes

From Gandoor Wiki
Jump to navigation Jump to search

Due to junking policies once practiced by the GBC, many episodes of the long-running Gandoorese science-fiction television program The Professor broadcast between September 1958 and May 1970 are missing from the GBC's archives. As a result of these junking policies, 104 of 327 episodes of The Professor, primarily from programmes 2 to 5, are considered to be lost, with programme 1 being the only programme of the series from this time period to have all of its episodes survive to the present day.

Background

When The Professor debuted on GBN on 13 September 1958, the GBC maintained no formal archival system for its television programming, with GBN programming only being archived until they were marked for either wiping (for programming recorded onto videotape, to enable the reuse of the 2-inch videotape to record other programming) or discarding (for programming recorded onto film). This practice of junking was by no means exclusive to the GBC, with many examples of television programming from both Gandoorese and foreign television networks being lost due to the junking of videotapes and film by television companies. Notably in Gandoor, 208 of 375 episodes of the popular drama series Rose broadcast on ATV from 1950 to 1957 have been lost due to the junking of kinescope recordings.

In the case of The Professor, the series was considered by the GBC to be a 'low-priority' program and therefore episodes were recorded onto 2-inch videotape, as opposed to the more expensive 16 mm film used to record higher-priority programming. As GBN was facing severe budget issues on account of the general economic crisis facing Gandoor at the time, the GBC was keen to reuse videotape whenever possible, with the first episode of The Professor to be marked for wiping being 'Chumbles', the 6th episode of programme 2, on 2 March 1959, only one month after the episode was originally broadcast on 24 January 1959.

Despite the establishment of the GBC-managed Gandoorese Television and Film Archives on 3 March 1959, this junking policy remained mostly unchanged until the establishment of an organized archival system for GBN in May 1962, between the conclusion of programme 5 in February and the premiere of programme 6 in July. After the creation of GBN's own internal archives, the policy was changed so that only low-priority programming could be junked under the following conditions:

  • It had been at least two months since the program was broadcast
  • The executive producer of the program has confirmed that they have no plans for rebroadcasting the program

In any case, the junking of episodes of The Professor significantly slowed down starting with programme 6. In contrast to programmes 2 to 5, which are missing a total of 63 of their 101 episodes, or 62% of their episode count, programmes 6 to 14 are only missing a total of 41 of their 221 episodes, or 18.5% of their episode count.

The GBC's junking policies came to an official end on 1 September 1970, when legislation went into force mandating archival of all television programming and movies in the Gandoorese Television and Film Archives. The last episode of The Professor to be wiped was 'Storms of Arrakis', the 25th episode of programme 14 on 11 August 1970, only three weeks prior to archival of television programming being made mandatory in Gandoor.

Missing episodes

List of missing episodes

As of March 2009, there are 104 episodes of The Professor that are no longer held by the GBC. The majority of the missing episodes come from programmes 2 to 5, which currently lack 63 of their 101 episodes. In contrast, programmes 6 to 14 currently lack 41 of their 221 episodes. As far as individual programmes go, programme 4 is the most affected by episode loss, with only 5 of its 26 episodes surviving to the present day. With the exception of the entirely extant programme 1, programme 11 was the least affected by episode loss, missing only 2 of its 26 episodes.

Of these missing episodes, 37 episodes have surviving clips and 38 episodes, including some episodes which also have surviving clips, have their entire audio soundtracks surviving due to contemporary recordings by home viewers.

Recovery

Episodes

A number of previously missing episodes of The Professor have been recovered since the GBC officially ended its junking policy in September 1970. When GBN's archives were first audited by the GBC in 1974, there were 138 episodes of The Professor from programmes 1 to 14 that were found to be missing from the archives. 34 of these previously missing episodes have since been recovered and returned to the GBC from a variety of sources, both from within Gandoor and from the United States, Canada, Australia, and New Zealand, where the GBC had had some success selling the series to independent stations in the United States, CTV in Canada, the ABC in Australia, and the NZBC in New Zealand during the 1960s. Episodes sold to the United States and Canada were provided to broadcasters via videotape copies of the original NTSC master tapes and episodes sold to Australia and New Zealand were provided to broadcasters via 16 mm kinescope recordings.

Sources of recovered episodes

Since the first audit of GBN's archives in 1974, a number of episodes which were absent from the archives have since been recovered from a variety of sources.

Gandoor
Gandoorese Television and Film Archives

Shortly after the completion of the audit of GBN's own archives, the GBC checked the Gandoorese Television and Film Archives for pre-September 1970 episodes of GBN programming. This search of the GTFA resulted in the recovery of eight episodes of The Professor: two from programme 1, the 10th anniversary special, two from programme 13, and three from programme 14. The recovery of the two episodes from programme 1 - episodes 2 and 5 - resulted in that programme being complete in GBN's archives and the only programme until programme 15 to survive in its entirety.

Private individuals

The episodes 'The Silver People' - episode 5 of programme 5 - and 'The Creators' - episode 3 of programme 7 - were returned to the GBC in 2001 and 2003 by two separate individuals. Both recovered episodes were 16 mm kinescope recordings of the original master tapes and the individual who returned 'The Silver People' said that he had been given the episode, along with several other 16 mm kinescopes of GBN programming, by his uncle, who he said had worked for the GBC from the 1960s to the 1980s. The individual who returned 'The Creators' says that he bought the episode at a jumble sale in 1991 because he had enjoyed watching The Professor as a child and was not aware of the existence of missing episodes until reading about the recovery of 'The Silver People' online in 2001.

Foreign countries
Foreign broadcasters

The GBC began to offer The Professor for sale for foreign broadcast in late 1960, starting with programme 4. Ultimately the series would be sold to a variety of independent stations in the United States, CTV in Canada, the ABC in Australia, and the NZBC in New Zealand starting in early 1961. As the United States and Canada used the same television standard as Gandoor, episodes sold to those countries were provided as videotapes copied from the original NTSC master tapes. For Australia and New Zealand, which used a different television standard, episodes were provided as 16 mm kinescope recordings.

Appealing to the networks which had purchased the series to search their own archives and return any episodes of The Professor to the GBC resulted in the recovery of the episodes 'Comet Sumnus' and 'The Time Bomb', episodes 17 and 18 of programme 6, from the NZBC in New Zealand in 1975. This was followed in 1977 by the recovery of the episode 'The Evil Skals, Part 5', episode 21 of programme 7, from the ABC in Australia; the recovery of five episodes, including four episodes from programme 4 - which only had a single surviving episode in GBN's archives - from CTV in Canada in 1978; and the recovery of the episode 'An Unusual Nova', episode 25 of programme 7, also from CTV, in 1979.

Recovery from foreign broadcasters continued into the 1980s and 1990s. Four episodes, all from programme 11, were recovered from an independent station in the United States in 1981; another independent station returned episodes 6 and 7 of programme 5 in 1985; episodes 10, 17, and 18 from the same programme were recovered from CTV in 1991; and episode 2 of programme 7 and episode 19 of programme 8 were returned from two separate formerly independent stations in 1994.

Private individuals

In 1976, a 16 mm kinescope of 'The Invasion', episode 25 of programme 5, was sent to the GBC from Australia. Alongside the episode was a note from the sender, who wished to remain anonymous, which said that they were an employee of the ABC and had taken the episode home when they were ordered to dispose of the recording in 1972 and remembered they had an episode of the series when they heard that the GBC had sent a notice requesting that the ABC search for episodes of The Professor in their own archives the year prior.

A 16 mm kinescope of the episode 'Deep Trouble', episode 10 of programme 8, was returned to the GBC by an Australian collector in 1986. The collector said that he purchased the episode at a flea market in Adelaide in 1981 for AU$15 from a seller who had 'a variety of 16 mm copies of television programming for sale'.

The most recent recovery of missing episodes of The Professor occurred in 2009, when episodes 2 and 3 of programme 6 were returned by a New Zealand collector. As these two episodes were from the same programme as the episodes returned to the GBC by the NZBC in 1975, it is thought that these episodes were taken from the NZBC around the same time period, likely by someone who had been ordered to dispose of them.

Clips

37 missing episodes are represented by what the GBC terms 'film extracts', short orphaned clips of episodes that have been recovered from various sources. The most common source of these film extracts is the GBC themselves, with clips being recovered from surviving episodes of other GBN programming or, less commonly, from being used in promotional trailers for The Professor that managed to avoid being junked. Other sources of film extracts include portions of episodes that were physically excised from the 16 mm kinescopes used in Australia and New Zealand due to local content laws in those nations and several examples of silent clips taken by physically recording the television screen with an 8 mm home camera during an episode's broadcast.

Audio soundtracks

38 missing episodes have their entire audio soundtrack surviving due to contemporary recordings by home viewers, including 19 episodes which also have extant film extracts. These audio soundtracks, including the soundtracks to two episodes which were later recovered, were released by the GBC on either cassette tape or CD between 1994 and 2006, with each release featuring linking narration by Tom Williamson to describe actions and other originally visual sequences. These releases would later be rereleased under the 'Deluxe Missing Episodes' range on both CD and digital download from 2009 to 2016. The Deluxe Missing Episodes releases of the missing episode soundtracks included additional interviews with surviving cast and crew members and bonus PDF materials about the episodes.
