• He wrote and staged the 1946 play Born Yesterday, which ran for 1642 performances; and the screenplay of the 1950 film adaptation.
• He directed the 1955 play The Diary of Anne Frank, which ran for 717 performances.
• He directed the 1964 musical Funny Girl, which ran for 1348 performances.

He was a colleague of Thorton Wilder, who mentored him, and an admirer of the work of Frank Capra. Kanin said "I'd rather be Capra than God, if there is a Capra." Kanin died at age 86 in New York City.
