Okay, as far as updates go, all I could find was updates on the game that was recently released on april 11, 2006. Game was released from Bandai and supposedly isn't that great. I've haven't personally played it, but it's supposed to be pretty good, excluding the graphics...

The Good: A delightfully weird sense of style; story and dialogue seem right at home with the anime's sensibilities; combining the music with the combo system makes the combat more interesting; three full storylines to play through.

The Bad: Combat remains button-mashy and easy at practically all times; graphics aren't very impressive technically; pacing will drive some people crazy.

As far as a movie goes, I don't think there's going to be one. Who knows. Cowboy bebop ended without any updates or follow threws untill a year after...
