10 Funniest Things That Happened During The Making Of Harry Potter

Rupert Grint's unflattering drawing wasn't the only time he got into a spot of bother with Alan Rickman. He also made a bit of a blunder during the making of The Goblet of Fire as well.

For reasons that aren't entirely clear, Rupert and Matthew Lewis (the actor who plays Neville Longbottom) were inside Rickman's car at one point. And, somehow, the two teenagers managed to spill milkshake all over the place. Of course, Rickman could hardly fail to notice what they'd done, and he became slightly paranoid about something similar happening again.

So, when he bought a brand-new BMW, he banned the two boys – and the rest of the cast, for that matter – from going anywhere near it. Whilst there was no official ban, Rickman made a habit of intimidating his fellow actors to stop them from ruining his new car.

Though Rupert and Matthew obviously didn’t mean to spill the milkshake, Rickman’s response was perfectly reasonable, all things considered.
