This was one of my top films for 2003. In general I am not a fan of the Farelly brothers, but I had enjoyed Shallow Hal, and Stuck on You got good reviews from our local paper, which is rare. One thing that had impressed me about Shallow Hal is that the things that you would think were completely illogical were addressed reasonably. The most obvious thought with the casting was that Matt Damon and Greg Kinnear are not even that close in age. Sure enough, early in the film they explain that Matt's character has most of the liver, so Greg's character is aging faster. I don't know if it is scientifically sound, but it works in the context of the film. That is one thing that is nice about the movie. The film has plenty of sight gags and easy humor, but there are also obscure references and delightful surprises that remind you that the film has a brain. It also has a heart, and Damon and Kinnear have a nice brotherly rapport.
Of the supporting cast, Eva Mendes is easily the most fun, and gets the best lines. There are also enjoyable turns with Meryl Streep, Griffin Dunne, and Cher starts out as her own worst caricature, but ends up showing a heart as well. Many other familiar faces pop up, including people you have seen as bit parts in the directors' other films.
Finally, I have to say I was really impressed with the connection between the two bodies. Very realistic looking make-up job.
