I have heard this as well, R2-D2 is the person telling the tale: "A Long time ago...." However, I cannot find where this is written? Wookepidia, Wikipedia, Starwars.com
Does anyone know where it states this about R2?
I've heard this as well, though purely as a fan theory. It actually makes a lot of sense, and helps explain a lot of the crap from the prequels. After all, he got seriously messed up on a regular basis during Episodes 4-6, up to and including taking a pair of heavy anti-ship lasers TO THE FACE, so I'm certain his memories are more than a little fragmented in spots. Add to that the fact that he would have had to piece together bits he wasn't present for from secondary sources and a fair bit of editorializing(clearly, he thought Jar-Jar was an *******), and we've got the conclusion that overall events happened the way he described, but a lot of the weirder details may simply be figments from the mind of a really old laser-addled droid.
This I REALLY want to believe...! It would also help make a retcpn of the prequels possible. Please, make it happy, Disney..!
