It's in the Bag! is a 1945 comedy film featuring Fred Allen in his only starring film role. The film was released by United Artists at a time when Allen was at the peak of his fame as one of the most popular radio comedians. The film has been preserved by UCLA Film & Television Archive.

The film is loosely based on the comic novel The Twelve Chairs (1928) of Ilf and Petrov, later filmed by Mel Brooks as The Twelve Chairs (1970). The team of screenwriters included Jay Dratler, Alma Reville, and Morrie Ryskind. Allen's encounter with Jack Benny in the film is notable as at this time they were involved in a famous 'feud', which ran for over a decade.
