He may be right, but the play is no cakewalk. For Rudd, Long Day's Journey must look like the north face of the Eiger. "I don't look at it as a way to gain theatrical credibility," he says. "Yet being in a play as big and as daunting as this for a long run is more fulfilling than being in a film. "I need the familiarity, the challenge, the routine. There's something very grounding about having to go to the same place every day and seeing the same people. I was in Alfred Uhry's The Last Night of Ballyhoo for a year. I like that 'going-to-the-office' aspect. "I also like the idea of doing a five-month stint in London. Both my parents happen to be from London. I've got family here. I've always liked the city, but I've never really lived here. "But that doesn't mean that I begrudge films," insists the Kansas-reared Rudd. "You are paid good money to fall in love with complete strangers."
