I live in LA, and I even work in the funeral business, so I’ve seen most of the Hollywood graves. Pretty much everyone at the Forest Lawns, Hollywood Forever and Westwood Memorial. Home of Peace in East LA has quite a few as well. Curly and Shemp from the Three Stooges are there. I noticed a small private mausoleum outside the main mausoleum that said “Warner” on the outside, so I peeked in. Sure enough, it contained three of the four original Warner Bros. (No Albert).
I’ve seen Clyde Barrow’s tombstone in Dallas–“Gone but not forgotten” on tombstone.
