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)
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.
