Comic Russell Brand is convinced his rise to stardom was delayed because his addiction to heroin stopped him taking his career seriously.
The funnyman landed a series of major acting roles after appearing in 2007's St Trinian's, starring in films including Forgetting Sarah Marshall and Bedtime Stories.
And Brand is convinced he could have reached international fame earlier if he hadn't become hooked on drugs.
He tells Britain's The Sun, "If you're addicted to heroin it takes up an awful lot of your time. You have to get the heroin, take the heroin, fall asleep because of the heroin, then more heroin. So I think I was unable to (become famous) because I was involved in a lot of other time-consuming things. I think that's the simple answer.
"I was a petty criminal and drug addict for a long while and if you're a drug addict it's very difficult to succeed in anything".
