He passed away due to renal failure. He's one of those guys that lived a surprisingly long time and was always in surprisingly good shape for his age, right to around the end; especially considering he already looked like he was in in his 60's or 70's by the 1950's (he played Kirk Douglass's father in 1958), and has always been overweight.
Sad to see him go, he will always remain one of the most entertaining actors of his time.
