London, Nov 21 Veteran actor Richard Griffith has jokingly said that he is so jealous of his younger co-star Daniel Radcliffe that he harbours violent tendencies towards him.

The 61-year-old, who stars alongside the 19-year-old in the Harry Potter films as Uncle Vernon Dursley and in Equus, where he plays the psychiatrist Dr Martin Dysart, said that being around the younger actor can sometimes be frustrating.

"I've no time for youth. It's a source of envy and despair. Daniel comes raving to me about the latest band he's been listening to and I have no idea what he's talking about. It just makes me feel so old," the Daily Star quoted him, as saying.

"In fact, I shall have him beaten soundly before I go home. I mean he's young, handsome, successful...everything unbearable," he added. (ANI)
