Cameron Douglas, 37, was released to a halfway house in July (16) after serving more than six years in the U.S. prison system for drug offences.

He was initially sentenced to a five year prison term for possessing heroin and selling other drugs in 2010, but his sentence was increased after he confessed to smuggling illegal substances into jail.

Michael, 71, adds that Cameron, his son by his first wife Diandra Luker, is keen to resume an acting career which notably saw him star alongside his father and grandfather Kirk Douglas in the 2003 comedy It Runs In The Family.

"He spent seven years in prison as a non-violent drug offender, approximately two years in solitary. Cameron, now that he is out of prison, definitely wants to get back into acting and had a decent career going before," Michael tells breakfast programme Good Morning Britain in a yet to be aired interview.

On how his son is coping after his release, the Falling Down star says, "He (Cameron) is doing great, and I'm sure there'll be time for him to tell his story when he is ready to."

Michael is set give U.K. film fans a unique insight into his life and career by joining British broadcaster Jonathan Ross on for a lengthy interview and question and answer session at London's Drury Lane Theatre on 30 October (16).

Of the event he says, "I'm so looking forward to being in London at the renowned Drury Lane Theatre with a chance not only to share my stories but also answer questions from my British fans."

As well as Cameron, Michael has two children, Dylan, 16, and Carys, 13, with current wife Catherine Zeta-Jones, 46.
