Well, I didn't mean to be disrespectful, but come on; how the hell would you know who Kenny Baker is unless you call him the 'midget in the R2-D2 costume'? IMHO, it really isn't as big of a deal as the other celebrity deaths this year. I mean, really; his filmography doesn't go very far past Star Wars. The only other notable movies he was in are Amadeus, The Elephant Man, and Time Bandits, and, even then, it was in very small (pun not intended) roles in the first two (and he was flat-out uncredited in the first one).
EDIT: Okay, that was a bit dickish. Anyway, I should probably request that the mods change the thread title to 'R2-D2's actor died' and maybe edit the OP a bit.
