What film coined the term "cameo appearance" for a brief star turn in a movie?

"Around the World in 80 Days" (sometimes spelled as "Around the World in Eighty Days") is a 1956 American epic adventure-comedy film starring David Niven and Cantinflas, produced by the Michael Todd Company and released by United Artists.

In the film, over 40 famous performers make cameo appearances, including Marlene Dietrich, George Raft, and Frank Sinatra. Promotional material released at the time quoted a Screen Actors Guild representative looking at the shooting call sheet and crying: "Good heavens Todd, you've made extras out of all the stars in Hollywood!" Shirley MacLaine and Glynis Johns are the last surviving members of the entire cast.

The term "cameo appearance" was invented by producer Mike Todd to persuade people like Frank Sinatra, John Gielgud, Marlene Dietrich, Peter Lorre, Buster Keaton, Joe E Brown and dozens more that playing a few seconds role would be worth their while.

The role of Passepartout was greatly expanded from the novel to accommodate Cantinflas, the most famous Latin-American comedian at the time, and winds up as the focus of the film. Cantinflas was billed as the lead. According to the guidebook, this was done because of an obstacle Todd faced in casting Cantinflas, who had never before appeared in an American movie and had turned down countless offers to do so. Todd allowed Cantinflas to appear in the film as a Latin, "so," the actor said himself, "...to my audience in Latin America, I'll still be Cantinflas."
