Former drugs baron Howard Marks is adamant a new biopic of his life doesn't glamourise smuggling - he hopes the movie will turn gangsters away from a life of crime.
The Welsh writer built up a worldwide cannabis empire in the 1970s and '80s and was sentenced to 25 years in prison when he was finally busted by the U.S. Drug Enforcement Administration in 1988.
He was released on parole in 1995 and penned a bestselling autobiography which has now been made into a movie, Mr. Nice, starring Rhys Ifans - and Marks insists the film highlights the negative aspects of drug dealing.
He tells Sky News, "Going to prison, missing your family. I think it's important, particularly for anyone thinking of undertaking it as a career, to know that you're going to likely end up with that kind of pain."
