Much as we loved his Uncles Vernon and Monty, the actor shone brightest on stage, where he infused his roles with intelligence and witThe BBC chose to announce the death of Richard Griffiths today by saying that the "Harry Potter actor" had died, but there was much more to Griffiths than his performance as the odious and self-satisfied Uncle Vernon Dursley in the Harry Potter movies, or even his gloriously memorable turn as the lascivious Uncle Monty in Bruce Robinson's cult movie, Withnail and I.He was terrific in both, but first and foremost Griffiths was a great stage actor who will always be remembered for his Olivier award-winning performance as the deeply flawed Hector in Alan Bennett's The History Boys.
