Daniel Radcliffe has revealed he relied heavily on alcohol towards the end of and straight after his stint as famous wizard Harry Potter.
In a tale as old as showbiz itself, Radcliffe rocketed to fame in 2000 at the tender age of just 11 as he landed the role of the bespectacled hero of JK Rowling’s series of children’s novels about witches and wizards who learn magic at a school called Hogwarts.
The books were already hugely successful, but the Potter franchise was elevated to household status with the success of the movies, which also starred Emma Watson and Rupert Grint alongside the cream of British acting royalty.
But Radcliffe grew up very much in the public eye, with the final Potter film Harry Potter and the Deathly Hallows part 2 coming out in 2011 when he was 22, and he admits he took to drinking due to the “panic” of not knowing where his career was going.
Speaking on BBC Radio 4's Desert Island Discs he said: "I definitely think a lot of the drinking that happened towards the end of Potter, and for a little bit after it finished, it was panic and not knowing what to do next, and not being comfortable enough in who I was to remain sober."
However, he does admit he often wonders if he’d have drink even if he wasn’t famous.
He said: "I will always be fascinated and frustrated by the question of: is this something that would have happened anyway or was this to do with Potter?
"I will never know. It runs in my family, generations back. Definitely not my mum and dad, I hasten to add."
The now 30-year-old, who has starred in a series of hit movies since his role as Harry Potter came to an end, says he understands why child stars often turn to drink or drugs to cope.
He said: "I think a huge problem for a lot of people is they get into a situation where they start doing something when they're 10.
"They are committed for several years, and they stop enjoying it.
"They are, by that point, the breadwinner for their family, so multiple people are reliant on them continuing to do this job and they feel pressured into it.
"If they don't enjoy it they go 'well, I will enjoy all the other things this life gives me, even if I hate the work'. So I think that's why you can see people going to drugs.
"You can also just see people go to drugs and drink because it's fun and they're available and it seems like a good idea, and there's nobody around you talking about the consequences or being honest about that."
