Very sad to hear that actor, Richard Griffiths, has passed away. RIP. He played Uncle Vernon in the Harry Potter movies and Uncle Monty in Withnail & I. He was only 65, and apparently died after complications set in following heart surgery.
As Uncle Vernon in the Harry Potter films, he was famous for the catchphrases: 'I'm warning you' and 'justice!', and for pointing out that there is no post on a Sunday.
As well as his roles in the Harry Potter films and in Withnail & I, he also starred in Pie in the Sky (P2, P3, P4) and The History Boys.
