The original TV play was screened in 1967 as part of ITV's
Armchair Theatre series. This was followed by a first series of six episodes, a second series of fifteen episodes, a third series of nine episodes and a fourth series of thirteen episodes (in all, 22 black-and-white and 22 colour episodes). These were supplemented by a
1974 colour film re-working of the pilot,
A Magnum for Schneider, .and a 1981 feature-length TV movie,
Wet Job.
Pilot – A Magnum for Schneider (1967) Callan has been retired from an anonymous government agency known as "The Section", run by Colonel Hunter (the name "Hunter" is used as a code name for the current Section Chief, similar to the
C of SIS). The Section removes those who pose a danger to the public, by means of either persuasion, blackmail, extortion or death. David Callan had been the Section's top operative, but had become too curious about his targets and the rationale for their removal. The Section considered him vulnerable, volatile and dangerous, so had laid him off to a dead-end book-keeping job with an ungrateful employer. The pilot was novelised by its scriptwriter,
James Mitchell, who went on to write most of the TV series episodes. The book was published under the title
Red File For Callan in the US, and as
A Magnum for Schneider in the UK, the storyline being based around Callan's love for model soldier war games, an interest shared by his target, Schneider, a Hampstead-based arms dealer. The pilot, filmed in black-and-white, was later remade in colour in 1974 as the feature film,
Callan, two years after the television series ended.
Series 1: 6 episodes (1967) ABC commissioned a first series of six episodes in 1967. In the first episode Callan rejoins the section in an unofficial capacity. The series was characterised by Callan's stand-offish, barely-respectful relationship with his boss, Hunter, who schemed to retain Callan on his side, and would play him off in little divide-and-rule scenarios with or against his fellow agents. This was in an effort to maintain his control, although it wasn't always apparent that these ploys worked. Callan's underworld contact, Lonely (
Russell Hunter), developed into an unofficial
sidekick, whose shadowing qualities outshone his sense of personal hygiene, something Meres in particular took joy in pointing out. Lonely remained ignorant of Callan's real work and believed him to be something of a gangland villain.
Series 2: 15 episodes (1969) By 1969, ABC Weekend Television had, due to an enforced merger with Rediffusion, become Thames Television. A second series of fifteen episodes, which had already been completed by ABC, was therefore transmitted under the name of the new company. This run ended with "Death of a Hunter", in which the Section chief meets his demise, and Callan is shot – perhaps fatally. It had not been decided whether the show would return for a third series, so this device was used to leave open either the possibility of more stories in the future, or a way of winding-up the show. Two endings were taped, in which Callan either lived or died. In the end, Thames decided to bring the programme back in 1970, this time in colour, for a series consisting of a further nine episodes.
Series 3: 9 episodes (1970) The third series, the first in colour, saw Callan still recovering from having been shot and struggling to come to terms with his situation. Interviews with Snell (the Section's doctor) and poor shooting range results portrayed Callan as a barely-functioning human being, whose future with the Section looks to be in serious doubt. If Callan is to be of any use to Hunter, something has to spark him into life. In league with Meres' younger, brasher, edgier and unpredictable replacement, James Cross (played by
Patrick Mower), the new Hunter concocts a scenario whereby Callan's energies are incited into real emotions that can be turned against the enemy. The remaining eight episodes see the revitalised yet ever-more world-weary assassin cover more ground, including one episode where love comes unexpectedly into his life, and which has the (expected) unexpected ending.
Series 4: 13 episodes (1972) The final set of thirteen episodes was broadcast in 1972. This saw Callan develop further than before. An unsuccessful mission results in Callan being interrogated in a Russian prison but he is exchanged by the Soviets for one of their agents. Now he is known to them, he has become a liability. What to do with The Section's top agent is solved by promoting him to the position of Hunter – a post he dislikes as much or even more than actually serving under a Hunter. However, this move by his masters has motives, and he is eventually relieved of his duties after an incident in which he re-enters the fray as an agent, which was against the rules. He is replaced as Hunter by his predecessor. The final three episodes form a trilogy based around the defecting Soviet agent Richmond (played by
T. P. McKenna), which was sub-titled
The Richmond Files.
Reunion TV movie: Wet Job (1981) The 1981 feature-length television story
Wet Job, written by Mitchell and produced by
ATV (without the original theme music or logo), rounded off the saga with a positive ending to the story of Callan and Lonely. Callan has become the proprietor of a military memorabilia shop when he is recruited by the new Hunter for one more job. Alas, he has to do this alone: Lonely has become a dapper gent, engaged to be married, and with enough self-confidence to defy Callan's request for help. Callan gives Lonely a
Krugerrand as a wedding present. As the
nemesis,
George Sewell becomes the last character to be shot by Callan. In the end, Callan completes the task, survives, feels used again, and even ends up with a mature girlfriend (played by
Angela Browne).
