Daniel Radcliffe, best known for his role in Harry Potter, says he "really struggled" with fame and subsequently alcohol after becoming a household name.

The actor, who made his acting debut at the age of 10, spoke about his issues with drinking during an interview with Youtube channel Off The Camera Show.

The 29-year-old said: "There is an awareness that I really struggled with particularly in my late teens when I was going out to places for the first time where you would feel, again it could have largely been in my head but, you would feel watched when you went into a bar, when you went into a pub.

"In my case the quickest way to forget you were being watched was to get very drunk and then as you get very drunk, you become very aware that people are watching more now because I'm getting very drunk, so I should probably drink more to ignore that more."

He said that there is "no blueprint," for starting acting at a young age, and that he feels lucky that he enjoys what he does for a living.

Radcliffe added that the attitudes of British people made it hard for him to be himself in the UK, adding that he felt there was an expectation that he lived up to a classic image of what a Hollywood star should live like.

He told the show's host, Sam Jones: "In London, because I'm English, there's a sense of familiarity, particularity with rich, super-upper class people who will just grab you like you are theirs."
