Doug Jones
I was so delighted when I found out he was in this as Billy Butcherson. I'd grown to like him after seeing him in the Hellboy movies as Abe, and finding out that he's a favorite in the 'biz for playing weird, supernatural creatures, because he does so well despite wearing makeup and prosthetics. People have said he's also very nice in person and easy to work with.
Billy was such a crazy, weird, but likeable character because despite being a zombie and losing his head a lot, he actually was a good guy; and it's like, the first thing he says to Winifred after being brought back to unlife and cutting the stitches on his mouth, is to tell her to go to hell, hehehehe.
I actually didn't realize that Doug Jones had already been playing supernatural creatures this far back in history, so it was a fun discovery.
