Richard Griffiths, most famous as Uncle Dursley in the “Harry Potter” films, but most beloved as Uncle Monty in 1987’s Withnail and I, has died. He was 65.

Salon has a good obit, which notes he performed opposite Daniel Radcliffe again in a 2007 production of Equus in London:

“Richard was by my side during two of the most important moments of my career,” Radcliffe said Friday.

“In August 2000, before official production had even begun on Potter, we filmed a shot outside the Dursleys’, which was my first ever shot as Harry. I was nervous and he made me feel at ease.

”Seven years later, we embarked on ‘Equus’ together. It was my first time doing a play but, terrified as I was, his encouragement, tutelage and humor made it a joy.

“In fact, any room he walked into was made twice as funny and twice as clever just by his presence.”
