A Trigun movie? I'd camp out in Hollywood for half a year waiting for the premiere of that one. Otherwise, tv series and OAVs wouldn't generally make a good conversion to a movie, but anime movies to live action movies might not be so bad. An Akira remake, anyone?
And let's not forget that they've also already made a live action Wicked City, The Guyver, Dog of Flanders, Uzumaki, Sanctuary, and are planning one for Ninja Scroll.
