I was flipping through it when I found this creepy looking robot-troll-thing. apparently it's Yoda from Return of the Jedi...?!? That must've been him after he died!
The text to the right of him (as you can see in the photo above) says, "This animatronic model of Yoda is from the movie Return of the Jedi from the Star Wars series. Its many electric motors allow it to make realistic movements." And all this time I thought it was Frank Oz! Seriously, though, that five fingered, long armed freak is not Yoda, don't be fooled. Yoda's a short 'n' stubby puppet, not a robot.
In all the legal text at the very beginning of the book it says that they've tried their hardest to get permission and all of that for the photos, and they supply a list of the sources, sort of. This includes "Return of the Jedi Lucasfilm". Well, that'd be great for this book... if Yoda was a robot!
After seeing the Yoda impostor, it makes me skeptical about any of the other facts in the book. What else did they mess up on...? Really, though, I'm sure these kinds of mistakes are made all the time. Oh, by the way, here's a great photo of Darth Vader from Revenge of the Sith!
