The Kid (2000)

Rusty is chubby and gets picked on at school back in 1960. Trying to make sense of the situation Russ thinks it must be his job to help the younger Russ so encourages him to stop eating rubbish and takes him to a boxer to help him learn to fight his bullies. Russ' co worker Amy takes a great liking to Rusty, seeing in him qualities that are completely missing from his older self. Rusty picks up on the fact that Russ and Amy may have a future and in an effort not to lose out on such a lovely young woman he proposes to her himself. Unfortunately Russ comes along and events once again show him in an unfavourable light. Amy apologises to young Rusty and leaves. Eventually it dawns on Russ that maybe Rusty has been sent here to help Russ. Russ has blocked out his childhood memories so remembers little of his past life. His relationship with his father is not a good one. By spending more quality time with Rusty and encouraging the boy to tell him about his life back home Russ slowly begins to recover his memories. They aren't good. Russ takes the day off work so the two of them can enjoy their birthday together.
