Daniel Radcliffe Admits He was Drunk While Filming Several "Harry Potter" Scenes?

And NOW we know why Harry Potter had the confidence to defeat Lord Voldemort.  Straight up LIQUID COURAGE.  Homeboy was drunk the whole time. --According to DANIEL RADCLIFFE, he was drunk a LOT during the filming of the "Harry Potter" movies.  And even though he never drank on set . . . he was drunk when he got there, and drunk on film. (--The legal drinking age in Britain, where most of the movies were filmed, is 18.  Daniel is 22 now.)

 -Quote, "I went into work still drunk.  I can point to many scenes where I'm just gone.  Dead behind the eyes.  I have a very addictive personality.  It was a problem." --He says the other people on the film didn't realize he was drunk because, quote, "People with problems like that are very adept at hiding it.  It was bad.  I drank a lot and it was . . . nightly." --Now, he says, he's done drinking and has moved on  to a new vice . . . fantasy football? 

He was making the talk show rounds last week and he told WENDY WILLIAMS, quote, "I got introduced to fantasy football this year, which took my life away.  My girlfriend didn't see me for weeks."  (--You'll find a clip on YouTube.)

Daniel really is serious about his love for American football.  In fact, when he was on "Ellen" last Thursday, he made a $5,000 bet with her that the Giants would win the Super Bowl.  No word if she's paid up yet.
