Mark Wahlberg found it difficult working alongside Martin Scorsese on THE DEPARTED as the pair were "constantly struggling" with one another. The actor admits it was a harrowing experience behind the scenes of the Oscar-winning movie, because he had different creative ideas from the director. He says, "Marty and I were constantly in this struggle. I had problems with Marty. He was 'I'm Martin Scorsese... da-dee-da.' He was pushing me in different ways." And the star admits playing the role of foul-mouthed cop SERGEANT DIGNAM - which earned him a Best Supporting Actor Academy Award nomination - caused him to take his frustration out on the rest of the cast. Wahlberg adds, "But it wasn't just Marty. The whole time I was in the character so I was mad at everybody. It was LEO (DiCAPRIO), MATT (DAMON) and JACK (NICHOLSON). F**k Jack too. "We were able to laugh about it afterwards and we have a great relationship now and we're going to do other stuff in the future."
