Dominic Monaghan's Lost rows

'Lost' star Dominic Monaghan says in-fighting on the set of the TV show gets him down.The actor - who plays Charlie Pace - says he finds it hard when other actors don't pull their weight or get on each others nerves.He fumed to Newsweek magazine: "It's tough being involved in a shoot with a large cast."Just the sheer politics can drag you down. So-and-so is not getting screen time. So-and-so is not showing up on time. So-and-so isn't behaving well on set."That's the toughest thing-coming home and going, 'Well, I behaved OK, but three or four people didn't'."Meanwhile, co-star Evangeline Lilly says the tensions are exactly the same as you would get between members of a family.She revealed: "We're like brothers and sisters but there are days when you want to thank them for being in your life, and there are days when you want to punch them in the face."
