I'm amazed by Boba Fett's heavy presence on these lists. I mean, he doesn't say anything of interest or note, and he doesn't DO anything except have the idea of hiding in that space trash. His informing on Han & co to Vader takes place off screen to boot. After that, pretty much the next thing he does is get shot and fall into that sphincter thing in the sand. He's a fleshless cog, a plot-tool.
Well, this isn't purely for movie characters and Boba has done a lot in the EU novels and comics.
