$7 Million dollars to sleep with Uma Thurman

Still, she's Uma Thurman and she was the mother of his children.

She isn't. Very average looking woman. Neither have really gone public about what caused the split, but I will put on my Dr. Freud hat and analyze it. Ethan went from the A-list superstar Uma Thurman with model good looks and height close to 6'. Ethan Hawke, on the other hand, has slightly above average looks, is actually shorter than Uma (and she towers over him with heels on), and he has a decent career in Hollywood, but the only mega-hit he was involved in was Dead Poet's Society where he wasn't even the lead. Everyone knows him from Training Day, but financially, that movie barely broke even. They divorced in 2005. Since Training Day in 2001, Hawke had been involved with a series of films that bombed or were never even released (Chelsea Walls, The Jimmy Show, Taking Lives, Assault on Precinct 13, One last thing). The only movie that was even a modest success was 'Before Sunset'. Meanwhile during this time, Uma had starred in Kill Bill volumes I and II and was one of the biggest stars in Hollywood getting paid big bucks for roles..

The Hawke left Uma for a woman that was the opposite of Uma in every way. She wasn't famous, rich, or breathtaking in attractiveness. She is also several inches shorter than Hawke. So basically, my analysis is that Hawke felt emasculated by Uma, and replaced him with a woman that would make him feel more like the man in the relationship.
