Having already played Hamlet, getting the lead as Jack, the main pup in Theatre Three's whimsical musical A Dog's Life, could have felt like a bit of a comedown. Gregory Lush, however, sank his canines into the part and made the show and his performance moving and memorable. The darkly handsome 36-year-old actor, a grad of UT-Arlington with an MFA from Ole Miss, has worked professionally in Chicago and Washington, D.C. Facing extended unemployment, he returned to Dallas last year and landed five consecutive starring roles. Besides the dog show, he was Professor Henry Higgins in T3's Pygmalion and the romantic lead in The Goodbye Girl. He recently played Uncle Ernie in Dallas Theater Center's huge production of The Who's Tommy. What next? "I would love to play Hamlet again," says Lush, who's also a teacher of Fitzmaurice vocal technique. "And Wolverine, if they ever make a musical out of the X-Men." Now wouldn't that be barking mad?
