Video: Watch: Father dresses up as Spiderman to surprise cancer-stricken son A terminally ill boy got the birthday surprise any boy could wish for: a real life Spiderman at his house. Mike Wilson dressed up as the web-slinging superhero to surprise his son Jaden on his fifth birthday. Jaden has a year to live after being diagnosed with a Grade 4 brain stem tumour. Mr Wilson, who is a parkour enthusiast and is used to scaling buildings, jumped from the roof of the family's Hampshire home to greet his stunned-looking son. After asking Jaden how old he is, the pair go inside to continue the birthday celebrations. You can't get a much better surprise than that.
