Anecdotes

Cast members Lee Patrick (Effie Perine) and Elisha Cook Jr. (Wilmer Cook) both reprised their roles from Le faucon maltais (1941).

Actress Stéphane Audran spoke about the film's failure, stating: "I didn't understand what happened on the picture. Everyone was fighting: George Segal, the director and writer, David Giler, the producer, Ray Stark. It's so difficult to do a good film even if the people are getting along well. If you have fights every day, it can't help."

Final theatrical feature film of Lee Patrick who played Effie.

George Segal repeatedly clashed with producer Ray Stark who was renowned for his hands-on approach.

Before the film was released, The Burbank Studios/Warner Bros took the REAL Maltese Falcon statuette from the 1941 version and made a model of it. They cast it in plaster, painted it flat black, wrapped it in Chinese newspaper and burlap (as per the Bogart movie), and mailed it to press reviewers as a gimmicky press promotion. They were all numbered and inscribed on the bottom, up to number 250, with EA-TBS (The Burbank Studios). Then somebody made a model from THAT one and sold them in book and movie shops, but the detail was lost in the process.
