Hyena

Can anyone point out in the doc a photo or video of the actor who plays Hyena-Swine? His name is Daniel Rigney and he passed away shortly after the film came out.

I'm disappointed he wasn't mentioned at all in the doc. He gave an amazing performance, and really held his own against Brando. He stole all the scenes he was in.

While all the other "manimals" mainly just hunched down and jumped around a little, he really played the part of an animal. I would love to hear more about his life on the set, and also if that was his voice (digitally enhanced of course) or if it was dubbed.
