Differences between the anime and the manga
In the manga, when Mewtwo rebels against Giovanni, Giovanni sends out his Rhydon and tries to kill Mewtwo by having it stab him in the chest. This ends up breaking Mewtwo's armor, releasing him from Giovanni's control. This scene is not present in the movie, and Mewtwo escapes from Giovanni without battling.
