Australian actor Guy Pearce has defended his latest film FACTORY GIRL and his co-star Sienna Miller against a barrage of scathing reviews. Pearce played artist Andy Warhol opposite Miller's Edie Sedgwick in the George Hickenlooper-directed movie. The film received a lot of negative reviews and critics have been mixed in their opinion of Miller's acting ability. Pearce says, "Most critical comments are completely unjustified. "They come from jealously. "Somebody like Sienna comes along who's clearly a very smart, very intelligent, brilliant, great actress... and her attitude, and mine, is 'Good luck in your next life guys.'"
