I don't mind it either actually. He's in trouble if his friends watch Cast Away, for about the 2 weeks it will take them to think 'this isn't funny anymore' and stop screaming 'Wilsoooooon'. Will for short, I think it's alright! Reminds me a bit of the neighbour in Home Improvement - he was pretty cool really.

ETA: But really, think of all the movies that will exist by the time his friends are old enough to be quoting movies...chances are our kids will never know about the movie Cast Away.
