Taylor Lautner doesn't think he could be in the 'Twilight' movies if he didn't get on with his co-stars.

The hunky actor - who plays werewolf Jacob Black in the vampire film franchise - insists he loves working with Robert Pattinson and Kristen Stewart and would find it hard to be on set if they all disliked each other.

He said: "The great thing about this series is how the whole cast is so close. It would be a nightmare if we weren't. It would be impossible to make this series because the characters are so tight. We're really thankful that we all get along so well."

Taylor had to bulk up to play Jacob in 'The Twilight Saga: Full Moon', in which he appeared topless, and while he's in no hurry to do it again, he may strip off once more in years to come.

He said: "If I have to strip off, if the character requires it, I will. Who knows, in 10 years time, I might do that. It's just all what the character requires."
