content: Enough people have summarized the plot so no need for that. What I liked about this film is the very smooth choreography between Damon and Kinnear. They really do move as if they've been together -- long enough. I don't know how many 'takes' it took, but the two actors were quite convincing as people who anticipated each other's moves and have worked out many of the logistics.There were scenes with very clever choreography of the conjoined twins playing football, boxing, hockey and in a bar fight. No doubt these scenes were to convey the message that conjoined twins can be good athletes.But as a film and a performance, those scenes showed that the film makers did think about the problems of being 'stuck together.' When the twins were separated, Matt Damon's character still walked sideways and often fell over because his brother wasn't there to balance him.Good acting, surprising from Damon, not known as a physical comedian.
