EXCLUSIVE: Charlie Sheen reveals all about that meltown, his HIV secret, family and big screen comeback

Hollywood bad boy Charlie Sheen has revealed big screen comeback plans after admitting for the first time that his public 'meltdown' was a result of dealing with his HIV secret.

In a rare and exclusive interview ahead of his one-night only West End appearance - in association with our WOW247 entertainments section - he has given an insight into what fans can expect.

And he won't be shying away from any tough questions.

An Evening With Charlie Sheen, hosted by Piers Mogan, a Rocco Buonvino and EJB Events presentation, is at London’s prestigious Drury Lane Theatre on Sunday, June 19.

The A-lister star of blockbusters like Platoon, Wall Street, Young Guns, Hot Shots! and The Three Musketeers, who then became the world's highest paid TV star at $1.25m an episode for comedy sitcom Two and a Half Men, will share his passion for acting, producing and writing.

In our chat - listen to it in full online - he gave details of his comeback film later this year, which will see him alongside Whoopi Goldberg, trapped in an elevator in the World Trade Centre's North Tower during the 9/11 attacks.

The 50-year-old says he would also like to work again with his "hero", his legendary actor dad Martin Sheen, who has stood by him during the bad times. And he hopes there's chance of rekindle movie glory with Platoon and Wall Street director Oliver Stone.

But he also spoke openly about his personal life, which has been all over the headlines, revealing details of his part in exciting new clinical trials of a once-a-week drug to keep his HIV condition at bay.

Blackmailers stung him for a reported $10m to keep his HIV positive status a secret, until he went public in November.

In the wake of his dismissal from Two and a Half Men came a highly publicised meltdown, in which he made bizarre statements in television interviews, suggesting that he was a "warlock" with "tiger blood" and "Adonis DNA". In another he was a "rock star from Mars". He posted videos to YouTube showing himself smoking cigarettes through his nose, and cursing out his former employers.

Now on the road to putting all that behind him he admitted it was the pressure of hiding his diagnosis and keeping it to himself that sent him off the rails.

When I put that to him he replied firmly: "Absolutely. Yes. There was something coming down every day and it was just a kind of an in order response way of dealing with it.
