Richard Griffiths, the versatile British actor who played the boy wizard's unsympathetic Uncle Vernon in the "Harry Potter" movies, has died. He was 65.
Agent Simon Beresford announced Friday that Griffiths died a day earlier of complications following heart surgery at University Hospital in Coventry, central England.
He paid tribute to Griffiths as "a remarkable man and one of our greatest and best-loved actors."
Griffiths appeared in dozens of movies and TV shows, but will be most widely remembered as a pair of contrasting uncles -- the hero's grudging Muggle guardian in the "Harry Potter" series, and flamboyant Uncle Monty in 1980s cult classic "Withnail and I."
"I was proud to say I knew him," said  Daniel Radcliffe.
