The above quote is from Jake Lloyd in his talk at the Denver celebration.
Lloyd said that he was able to keep one of his costumes and several lightsabers.
The first scene they actually filmed with him was of him and Jar Jar together...only Jar Jar wasn't really there. So Jake's first shot on the movie was actually some of the more difficult acting work he had to do.
Jake also confirmed that his sister, Madison Lloyd, would be in the film as Princess Ellie.
