There has been a lot of information bouncing around the web about Michael O'Kelly's recent stage production Live Forever: the Ray Bradbury Odyssey. Whereas a number of Bradbury's own books and plays have autobiographical elements, this seems to be the first attempt to present an outwardly biographical play about Bradbury himself, albeit with a fantastical treatment.The most interesting article I have seen so far is this one from the Ventura County Reporter, which also mentions film director David Zucker and his stated aim of getting a film version of the play off the ground.
Audio update: Colonial's Martian Chronicles audio adaptation now has a release date - 7 June 2011 - and is available for pre-order from Amazon.
