Well, appropriately enough, Brian Cox is featured in Tom Stoppard's new play "Rock And Roll". He's also noteworthy for being the first actor to play Hannibal Lector (in Michael Mann's "Manhunter"). He did a fantastic turn as screenwriting guru Michael McKee in "Adaptation". Perhaps you saw him as the demon girl's tragic father in "The Ring"?
He sounds like a real fan despite getting the PS release date wrong.
