Corrected entry: Qui-Gon, Obi-Wan and Jar Jar travel through the planet Naboo's core to get from the Gungan City to Theed. Two points: 1) If the planet's core isn't molten, the surface should be frozen and uninhabitable. 2) Even if it's water all the way down, the pressure would eventually reach hundreds of tons per square inch and squish our heroes like bugs.
Corrected entry: When Qui-Gon is talking with Watto about thier bet after the race (on a balcony above the track) you can see Qui-Gon move to the edge of the balcony. He stands there for a moment and then moves back in just in time to miss being spotted by one of Darth Maul's probe droids! Jedi intuition, or just good luck? (01:10:41)
Correction: The probe droid DID see Qui-Gon during its flyby. This is why Darth Maul gets on his hoverbike and rides off when the probe droids return to him - because he now knows where the Jedi are.
Corrected entry: If C3-PO is from Tatooine and R2-D2 was there, why in Star Wars are they completely unfamiliar with the planet? How come R2-D2 doesn't know Obi-wan and Obi-wan doesn't recognise the robot that saved his life?
Correction: In "A New Hope", Uncle Owen tells Luke to take R2-D2 to get its memory erased as if the memory erase isn't a big deal at all. Most likely, in the thirty or so years between episodes 1 and 4, an owner of the droids did exactly what Uncle Owen wanted to do. Also, Obi-Wan must have worked with hundreds of droids in his career as a Jedi - this may be disproved in the forthcoming films, but for the moment we can only assume that R2-D2 was one of many.
Corrected entry: In the opening story text of The Phantom Menace, it refers to Obi-Wan and Qui Gon Jinn as Jedi knights- but Obi-Wan is still a padawan and not yet a Jedi knight.
Correction: He's a Jedi Knight in training and is ready for the trials. Close enough, particularly as the opening text must, by necessity, be brief.
Correction: And Qui-Gon is a Jedi Master. Like the other correction said, it's for brevity during the opening crawl.
Corrected entry: When Obi-Wan is hanging on to the ledge when he fights Maul, he sees Qui-Gon's lightsaber on the ground next to him. The design of the hilt is the same as Obi-Wan's. No two Jedi have the same hilt design.
Correction: There's no rule stating that Jedi must have a unique design - Jedi build their own lightsabres using whatever design they see fit to use. There's nothing to prevent Obi-Wan from building one similar to his master's sabre.
Correction: This could just be a Gungan phrase for going throught the underwater caves.
