The scene involving a topless Sue Ane Langdon and Sir Sean Connery near the beginning was the subject of a photo feature in Playboy Magazine.

The last feature film to be photographed by legendary cameraman Ted D. McCord.

This was originally intended to star either Albert Finney or Henry Fonda. Janice Rule was considered for the female lead.

Both Patrick O'Neal and Clive Revill later played murderers on Columbo (1971).

Sorrell Booke and Mabel Albertson would later co-star again in What's Up, Doc? (1972).
