So Dio's out of Brütal Legend and Tim Curry's in, but it has nothing to do with any ongoing feud between Dio and Ozzy 'Prince of Darkness' Osbourne, as speculated. Tim Schafer has issued a statement clarifying the reasons for the decision, stating that "Ronnie James Dio is an amazing singer and truly one of the great figures of Metal, but as the character of Doviculus evolved, we realized that Tim Curry was a better fit for the part."
That's all it is. He's a "better fit." Schafer claims that it was Curry's role as The Lord of Darkness in the 1985 movie Legend which landed him the part of Doviculus, but we suspect it may be his most famous role, as Rocky Horror's Frankenfurter, which is the real reason behind the casting. Just you wait, Doviculus will be prancing around in stockings and a corset before the game is through. Yeah, we see you shiver with antici ... you know the rest.
