Mike Todd is credited to have coined the word "Cameo" because it wasn't earlier used in the Film Industry Lexicon or any Movie till "Around The World In 80 Days" was released. Todd used this word to lure big stars in believing that appearing in little roles wasn't so small after all, and using this word he rounded up around 34 stars to to play what he called cameo roles. Some of the big stars he acquired for his film were Marlene Dietrich, Frank Sinatra, Peter Lorre, Noel Coward, Evelyn Keyes and many more top stars.
This is the second Todd-AO production (the first was Oklahoma! (1955)) shot twice, at 24 fps (to produce the general-release version in 35 mm) and at 30 fps (to produce the roadshow version in 70 mm). Both versions were shot on 65 mm negative with Todd-AO lenses. Sometimes two cameras operated side-by-side filming the same take, other times the same camera was used with the speed changed for the second take, and still other times, in non-dialogue scenes, the same shot was used. The 35 mm version is presented in conventional 2:1 squeeze anamorphic process (incorrectly credited to Todd-AO); the 70 mm version is presented in Todd-AO.
