Schwimmer does need some physical therapy to strengthen his lip, jaw and eyelid muscles. Maybe they were typecast here, but Barbara Hershey and Gwyneth Paltrow were perfect. Hershey just pulls you out of the movie and into someplace in the Dreamtime. She literally makes your heart ache. And Paltrow instinctually understands how to play her character. When she seems to know exactly what Tom is up to, but then doesn't, it's amazing. She does that 2 or 3 times in the movie, and I loved it each time. Nobody can play the ordinary, unaffected, trusting girl with a heart of gold who loves everybody and hates having to hurt anyone, while dealing with the unavoidable truth that she is, in fact, an unattainable, upper-class goddess who must slay men left and right, better than she does. All Schwimmer had to do, was be himself for it to work, and he almost blew that simple role by playing it excessively slack-jawed and loose-lipped. Will Ferrell could have done it much better. Extremely strong casting, except for Schwimmer and his mom, and some decent writing here and there make it work, however dopey the story is. The whole bit about the 2 Tom's mistaken identity, is excusable as it brings us Barbara hershey, and also gives Paltrow one of her opportunities to send Tom one of her knowing, accusatory looks, when she really suspects nothing.
