The actor has had few movie roles since being fired from his role in U.S. TV comedy Two and a Half Men in 2011 due to making derogatory comments about the show's producer Chuck Lorre.

In November last year (15) he explained his comments and subsequent public meltdown as being the result of an escalation in his drug and alcohol abuse problems caused by being informed he had contracted the HIV virus.

Charlie, who recently filmed his first movie since revealing his diagnosis, wants to work with his father Martin, 75, again as he attempts to return to major movie roles.

"He’s (Martin) one of my heroes," the 50-year-old star tells Britain's i newspaper. "If something, the right thing came up, absolutely – any chance to work with your family, especially when they are this talented. It’s always a gift."

Father and son famously worked together in Oliver Stone's 1987 financial thriller Wall Street, in which the younger Sheen played a headstrong stockbroker and the elder starred as his dad, a trade union leader.

Martin, who also suffered from alcoholism as a young man, praised his son's courage in admitting his HIV positive status and facing up to his problems.

"When someone comes to themself, they have the moment of clarity, and they reveal their secrets, which all of us have, in public, it is a great sense of relief. It is a miraculous occasion," the Apocalypse Now told the Naples Daily News after his son bared all on U.S. news show Today.

Charlie's comeback role is in Nine Eleven, a film about five people trapped in the North Tower of the World Trade Center during the infamous 2001 terrorist attacks which destroyed the New York City landmark and killed almost 3,000 people.

"I just finished the film about a month ago," Sheen says. "It’s pretty interesting. It’s a 9/11 film and it’s the first story told from the inside."

"It’s about five people in an elevator in the North Tower on the day of the event. It’s based on actual events. We’ve just finished that. I’ve just seen the rough cut and it looks fabulous."

Despite in the past stating his belief that Islamist terrorists were not responsible for the attacks, Charlie says the new movie will not delve into any conspiracy theories.

"We stay away from all that," he adds. "This is a real human interest piece and really honouring those we lost. It honours all the heroes."

Nine Eleven is scheduled for release later this year (16), and according to its star, will debut at a film festival on 11 September, the 15th anniversary of the attacks.
