Sir Ian McKellen's career has spanned playing characters as diverse as Shakespeare's "Hamlet" to comic book villain, Magneto in "X-Men".
The English-born actor's portfolio includes both stage and screen - he was given a Tony award and two Academy Award nominations.
McKellen is also an openly gay actor and has been a strident activist for lesbian, gay, bi-sexual and transgender rights.
He is currently performing in London in the stage production of "Waiting for Godot" until April 2010.
Here's your chance to ask him a question.
