I have to admit that I have never seen such a twisted movie about relationships. There was 'We don't live here anymore' however this is more twisted, that it van be passed as a thriller disguised as a love story. From the beginning to the end the movie is solely focused on 4 characters - Anna, Larry, Daniel and Alice. The twist occurs with the exchanging of partners back and forth amongst these 4 characters. Credit needs to be given to all these 4 actors. Clive Owen who plays the lustful Larry was my least favorite - I guess it was the nature of his character a pervert who gets what he wants. Julia Roberts, gives one of her 'natural' performances again, Jude Law played the 'wimp' if I am not mistaken for the first time, and Natalie Portman, who all credit should go to, gives the performance of her career I guess it was time she took the time off that Star Wars crap, to give something more worthwhile. However, I do not see much 'Oscar' potential for this film. It may have been really good, but not 'Oscar' worthy, I guess it should not have aimed for the Oscars - it would have definitely been more successful if it was released widely as a holiday blockbuster.
