DALLAS star Patrick Duffy is considering pulling out of a British Christmas pantomime after finding out it will not be staged in London as he thought. The 57-year-old actor, better known as oil tycoon BOBBY EWING in the hit 1980s TV show, signed to play servant BUTTONS in a production of Cinderella at the New Victoria Theatre in Woking. But the star is furious after discovering Woking is in the county of Surrey, 40 kilometres (25 miles) outside London. A source tells British tabloid The Sun, "Patrick was a little stunned. He thought it was in a nice part of London like Hampstead - not right out in the sticks. "He didn't look too happy when people started saying Woking was like Slough - the town in The Office."
