A boy makes a wish on a fairground machine to be ‘big’ and, next morning, he discovers he’s turned into 30-year-old Tom Hanks (Forrest Gump)! Much of the humour in the movie is derived from Oscar-nominated Hanks’s expert comic timing and his perfect depiction of the boy in an adult’s body.

Viewed through the eyes of a child, the complicated rules and rituals of life in the grown-up world – ambition, office politics, empty relationships – are put into perspective perfectly. Heart-warming, touching and very, very funny.
