Daniel Radcliffe Was Very Drunk on Set of HARRY POTTER AND THE HALF BLOOD PRINCE

Daniel Radcliffe may be proving himself as one child star who may be able to break the mold, but that doesn’t mean he hasn’t battled his demons.

In a new interview with British celebrity news magazine, Heat, Radcliffe admits that there was a period in his life where he was constantly drinking:

“I have a very addictive personality. It was a problem. People with problems like that are very adept at hiding it. It was bad. I don’t want to go into details, but I drank a lot and it was daily — I mean nightly,”

And while he never drank on the set of HARRY POTTER, Radcliffe said that he definitely did have to come into work drunk a few times:

“I can honestly say I never drank at work on ‘Harry Potter.’ I went into work still drunk, but I never drank at work. I can point to many scenes where I’m just gone. Dead behind the eyes.”

The 22-year-old actor said that while the fame was fun, there was a lot of pressure to keep up such a facade:

“I loved the fact I suddenly could talk to people and feel so entertaining and so interesting. But after a while, you’re living under such a cloud of shame about what you’ve done and the dread of who you might see, what you might have said to them, what you might have done with them…You either have to change something or give into that shame and I wasn’t prepared to do that at 21.”

Luckily, Radcliffe says that he’s been sober since 2010, after turning to POTTER costar Gary Oldman (who also battled alcoholism) for advice.  And now, his life is very simple:

“I just do my job and I go home. [Girlfriend Rosie Coker and I] go out to a restaurant but we don’t go anywhere that there’s going to be paparazzi…We don’t go to clubs, we don’t really go to bars. So, we just kind of hang out with friends and have dinner.”

Radcliffe’s new movie, THE WOMAN IN BLACK, is in theaters now.
