One, Two, Three

One, Two, Three is a 1961 American political 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, kettő, három by Ferenc Molnár, with a "plot borrowed partly from" Ninotchka, a 1939 film co-written by Wilder. The film stars James Cagney, Horst Buchholz, Liselotte Pulver, Pamela Tiffin, Arlene Francis, Leon Askin and Howard St. John. It would be Cagney's last film appearance until Ragtime in 1981, 20 years later.
