Last film role for Margaret Leighton, who had died by the time of the film's release.
Theatrical movie debut of Bernard Hill ("Blind" Freddie - beggar).
Originally titled "A Choice Of Weapons" - it was actually press-shown under that title, and reviewed with that title (only a few weeks in advance of its opening) in the "Monthly Film Bulletin" magazine published by the British Film Institute.
Released in the United Kingdom in a double bill with The Swiss Conspiracy (1976).
