1975 film by Douglas Hickox
Brannigan is a 1975 action thriller film directed by Douglas Hickox, and starring John Wayne, Richard Attenborough and Judy Geeson. Set principally in London, the film is about a Chicago detective (Wayne) 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 American detective uses his own brand of law enforcement to recapture the criminal.
It was one of many Dirty Harry–type films released in the wake of that film's success, featuring rogue cops who don't "play by the rules." Brannigan was filmed on-location in London and at Shepperton Studios in Panavision and DeLuxe Color. One of the screenwriters was Dalton Trumbo's son, Christopher Trumbo. This was the only British-produced film of Wayne's 50-year-career.
The film was distributed by United Artists on March 26, 1975 in the United States, and on June 12 in the United Kingdom. It received mixed reviews from critics, and was a commercial disappointment.
