3. Big
When it comes to body swap comedies, you won’t get better than this charming and funny tale of 12-year-old Josh Baskin. The youngster makes a wish to be “big” – and it comes true when he wakes up as an adult, played by Tom.
For the lead role, the star had to channel his inner pre-teen and make the audience forget they were watching a grown man – and he was easily up to the challenge. First released in 1988, Big remains a timeless favourite thanks to Tom’s adorable man-child.
