Look Who's Talking
Although he may not have been seen on screen in 1989's 'Look Who's Talking', Bruce was certainly the star of the comedy movie.
The film starred Kirstie Alley as accountant Mollie Jensen (Alley) who is left to raise her newborn baby Mikey alone after she falls pregnant to a married man called Albert (George Segal), however, taxi driver James Ubriacco (John Travolta) becomes part of the family after he drives her to the hospital when she goes into labour and inadvertently witnesses Mollie's baby be born. The twist of the movie being that the audience can hear Mikey's thoughts through the voice of Willis.
The original film cost $7.5 million but banked almost $300 million at the box office and went on to spawn two sequels, 'Look Who's Talking Too' and 'Look Who's Talking Now' - which featured the family's dogs talking in their heads - as well as a TV series 'Baby Talk'.
