Callan is a British action/drama television series created by James Mitchell, first airing between 1967 and 1972.
 It starred Edward Woodward as David Callan, an agent of a state secret service dealing with internal security threats to the United Kingdom.
 Though portrayed as having responsibilities similar to those of the real-life MI5, Callan's fictional "Section" has "carte blanche" to use the most ruthless of methods.
 In the storylines interrogation is by means of torture, while extrajudicial killings are so routine they have a colour-coded filing system.
 With the possible exception of "La Femme Nikita", no TV series has ever presented a Western government agency in so sinister a light as "Callan".
 Despite being an assassin who stays in the socially isolating job because it is the only thing he is good at, Callan is a sympathetic character by comparison to his sadistic upper-class colleagues and implacable superior.
 The downbeat cover for the Section's headquarters was the scrap metal business of "Charlie Hunter" (a reference to the Richardson Gang).
 Produced by ABC Weekend Television and Thames Television, the programme proved extremely popular; as well as four series between 1967 and 1972, there was a film in 1974.

 The series follows the lives of around forty survivors from the crash of Oceanic Flight 815.
 The survivors find themselves on a mysterious tropical island, and interact with a group known as the Others, who appear to have lived on the island since long before the crash.
 Tom is an influential member of the Others, and is introduced in 2005 in the season one finale "Exodus: Part 2", where he kidnaps one of the survivors.
 The character makes another fifteen appearances before being killed in the season three finale "Through the Looking Glass".
 Tom appears twice in season four in the flashbacks of other characters.
 Gainey was initially credited as playing "bearded man" and then as "Mr. Friendly" throughout season two before the character was given a first name.
 In a montage of deceased characters shown at Comic-Con in 2009, the "Lost" producers present the character's full name as "Tom Friendly".
