Invito a cena con delitto

The screaming woman sound used as a doorbell is Fay Wray's screams from King Kong (1933). Her unique scream has made her known as the "Scream Queen" of movies.

(at around 1h 14 mins) Milo Perrier tells Sam Diamond, "I'm not a Frenchy... I'm a Belgie," referring to the fact he is from Belgium and not France. However, in discussing Twain's annual poodle hunt in France, he implies that's his home country, and later he says, referring to himself, that you should "never underestimate a Frenchman's nostrils."

Opening credits: Starring (In Diabolical Order)

The original ABC Network broadcast of the film contained four additional scenes not found in the theatrical or DVD version. 1. Jessica Marbles' taxi driver (played by Peter Sellers) requests a large fare. 2. Dick and Dora Charleston narrowly avoid running over Tess Skeffington, who is walking back to Sam Diamond's car from a service station because she and Sam ran out of gas. Satisfied that Tess is all right, the Charlestons simply drive off, leaving her there. 3. When Willie Wang covers up the body of Twain, he finds a note in Twain's hand and smugly announces this to the others. 4. As the detectives drive away from Twain's house at the end of the film, Inspector Wang and Willie pass another car carrying Sherlock Holmes (Keith McConnell) and Dr. Watson (Richard Peel) heading towards the Twain home. When Willie asks his father "Why didn't you warn them?" Wang replies "Let idiots find out for themselves."
