OMG The Stuntman. Wow. Hadn't even thought about that one in years.
You want to know how good he was at portraying the madness of his character in that film?
Well - the actor Steve Railsback - ostensibly playing the "lead" role opposite O'Toole's mad director - was most famous previously for portraying Charles Manson in Helter Skelter!
And arguably (though it was part of the role) O'Toole out-crazied HIM in certain respects.
