We didn't notice before, but now we want to go back and watch the tapes.

In a new interview with British magazine Heat (via Reuters), Daniel details his history with alcohol and how it affected his filming of Harry Potter.

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

The 22-year-old actor made sure to clarify that he did not drink while on set of Harry Potter.

"I can honestly say I never drank at work on Harry Potter. I went into work still drunk, but I never drank at work," he explains. "I can point to many scenes where I'm just gone. Dead behind the eyes."
