Brannigan is a 1975 British action thriller film directed by Douglas Hickox and starring John Wayne and Richard Attenborough filmed in Panavision and DeLuxe Color. One of the screenwriters was Dalton Trumbo's son, Christopher Trumbo. Set principally in London, the film is about a Chicago detective sent to Britain to organise the extradition of an American mobster, who is soon kidnapped and held for ransom. Struggling with the restrained policing style of his British counterparts, the tough Irish-American detective uses his own brand of law enforcement to recapture the criminal.
