One, Two, Three is a 1961 American comedy film directed by
Billy Wilder and written by Wilder and
I.A.L. Diamond. It is based on the 1929 Hungarian one-act play
Egy, ketto, három by
Ferenc Molnár, with a "plot borrowed partly from"
Ninotchka, a 1939 film co-written by Wilder. The comedy features
James Cagney,
Horst Buchholz,
Pamela Tiffin,
Arlene Francis,
Leon Askin,
Howard St. John, and others. It would be Cagney's last film appearance until
Ragtime, 20 years later.
