Look Who's Talking is a 1989 American romantic comedy film written and directed by Amy Heckerling, and starring John Travolta and Kirstie Alley. The film concerns the relationship between single mother Mollie (Alley) and her infant son Mikey's babysitter, James (Travolta). Bruce Willis provides the voice of Mikey's precocious thoughts, heard only by the audience. The film also features Olympia Dukakis, George Segal and Abe Vigoda in supporting roles. Produced by M.C.E.G. Productions, Inc. and released on October 13, 1989 by Tri-Star Pictures, the film received mixed reviews from critics.

This success launched a titular franchise; including two sequels Look Who's Talking Too (1990) and 1993's Look Who's Talking Now! (1993), and a television series spin-off titled Baby Talk.
