Daniel Radcliffe claims that he is too old for partying.

The 20-year-old star no longer socializes with the rest of the Harry Potter cast and crew because he wants to carve out a career as a respected actor: “I used to play a lot of pranks in the past but I want to be a more mature, serious actor now. I don’t get involved with drinking or partying with the cast anymore.”

The actor also blasted stars who are only interested in fame, insisting he hates being “a celebrity.” He is quoted by Britain’s Daily Star as saying:

“I hate celebrity culture, but I’m unavoidably part of it. These people are celebrities as a by-product of what they do. People read every little thing about Peter Andre and Jordan and I couldn’t care less. They don’t want to work, have no interests, no passions, nothing and yet they seem to be held up on pedestals. I don’t think they should be trying to push themselves onto us. It does annoy me of course, but I’m part of it.”

Daniel’s serious attitude appears to be in contrast to his Harry Potter co-star Rupert Grint, who has been spotted at several UK music festivals this summer and makes no secret of his love of wild nights out.

Grint recently said, “When I’m drunk, I like to cause mischief. I’ll steal props like the broomsticks from the Harry Potter set and bring them out to the pub for comedy value. It seems funny at the time. Trouble is I usually get too trashed to remember what happened the next day.”
