I'd like to see a movie of the two also, but it'll probably be another decade or more before that'll even be considered. As far as who would win in the movie, my bet would be that they both win. 1. Typical crossover style where 3rd evil monster (or more) enters the picture, forcing G & G to team-up instead. Both win. 2. Godzilla cast as bad guy, threatens mankind, Gamera the good guy, attempts to save mankind. Godzilla eventually kills Gamera but Gamera's sacrifice somehow stops Godzilla's destruction in turn saving mankind anyway. Godzilla wins the fight, Gamera wins the objective. Both win.
