Blue/green screen Machinima: Yes, there's been a few films that have incorporated this technique. The film Peacemaker, by Rodrigo Olmos and Alex Schmidt, uses this technique extensively as they combined the lead character from one game, into another game entirely. The amount of work they put into this film is pretty amazing - they re-textured the environments behind the lead character, Fenimore Filmore (from The Westerner) with either green/blue textures so they could get a proper key.. You can check out the piece here: http://www.neueufer.com/machinima/movie03.htmThanks Paul! Oh, and the films are excellent; check them out!
Additionally, I used this approach as well (though not as polished as Peacemaker) when working on Strangerhood Studios with Rooster Teeth. I created a wallpaper and carpet in the Sims 2 that was fully green, so that I could key the main "Punk Cyborg" character over other backgrounds from the game itself.

Not sure if a Machinima film has ever incorporated the lead character over a live action plate. The reverse was done to some degree in Game:On, where they composited a live action car into the game space as part of the transition between live-action into Machinima.
By the way, Paul also mentioned he'll be at ACMI in May 2006 talking about Machinima. There's nothing listed on ACMI's online calendar yet, but Paul's certainly worth watching out for.
