According to Movie Hole Lucas has an idea for a prequel to The Phantom Menace where we would suffer through enjoy the adventures of the Jedi taking back control of the universe from the Dark Lords. Yoda would be the star guaranteeing two fun filled hours of puppet-on-speed action.
I don’t know what its name would be. Maybe Star Wars Episode 0: Rise of the Jedi or maybe Star Wars Prequel 1: The Greed of Lucas? Whatever it is, I don’t think I could stand to sit through an entire movie headlining Yoda in light saber battles, but then again, I did watch The Phantom Menace with the worst sci-fi character ever created, Jar Jar.
