Daniel Radcliffe drunk alcohol to help him deal with fame.

The 24-year-old actor turned to booze when he was filming the 'Harry Potter' franchise because he was struggling to cope with his new celebrity status and adoring fans.

In a new interview that will air on Sky Arts later this year, Daniel, who would turn up to filming still drunk from the night before, said: ''I would have benefited from not drinking as it was not making me as happy as I wanted it to.''

He added: ''It is not a real pressure but it is a pressure of living with the thought, 'Oh, what if all these people are saying I am not going to have a career? What if they are all going to be right and will be laughing and I will be consigned to a bunch of 'Where are they now?' lists?''

The hunky star, who has been teetotal since 2010, went on to receive critical acclaim for his theatre work and believes the fantasy film series, in which he played the title character, has opened up lots of career ventures for him.

He explained: ''People don't shout Harry Potter at me now, they tend to know my name, which is lovely ...

''... [but] I always will credit the opportunities I get to 'Harry Potter'. I would not be a happy person if I was bitter about those ten years of my life.''
