Richard Griffiths was 65. He was the versatile British actor who played the boy wizard's unsympathetic Uncle Vernon in the "Harry Potter" movies.
Older folks will know him best as Monty in Withnail & I, Brits will know him as Henry Crabbe in Pie in the Sky, and I remember him fondly as Dr. Albert S. Meinheimer and Earl Hacker in The Naked Gun 2 1/2.
