Mammy (1930) is an American pre-Code musical comedy-drama film with Technicolor sequences, released by Warner Bros. The film starred Al Jolson and was a follow-up to his previous film, Say It with Songs (1929). Mammy became Al Jolson's fourth feature, following earlier screen efforts as The Jazz Singer (1927), The Singing Fool (1928) and Say It with Songs (1929). The film relives Jolson's early years as a minstrel man. The songs were written by Irving Berlin, who is also credited with the original story titled Mr. Bones.
