Pterygotus

The Borgnine guess was good, though, considering how he appeared on Spongebob Squarepants...

I just found out that Chuck Yeager was alive from reading another thread here, but I'd probably known already and forgotten. I do tend to get him confused with Charles Lindbergh... Lindbergh was the one who hated Jews, I think.

Peter Cushing (Grand Moff Tarkin) bit it, sometime in the nineties I think. Cancer. Michael Sheard, who played Admiral Ozzel, died in 2005. Sad, but those are the only two I can think of, and I had to look on Wiki to get Sheard's name. SW actors seem to have a good track record as far as not dying goes.
