Midnight Run - Robert De Niro brings his acting skills to comedy. He plays a gruff ex-cop and bounty hunter who's paired with straight man Charles Grodin. The two guys, who can't stand each other, are stuck together for the duration of a journey neither of them wants to be on. 18 Again - 92-year-old George Burns plays 81-year-old Jack Watson whose birthday wish to be 18 again is granted when he wakes up in his grandson's body, while his own body remains unconscious in hospital after an accident. 18 Again is one of a number of role-reversal films coming out of Hollywood at the moment, replacing the craze for baby films. The most successful of these is Big, the surprise hit of the summer in America. Tom Brook reports on this trend and interviews Tom Hanks, star of Big.
