Steven Culp?

Probably for same reason why Kevin Bacon didn't appear for the first movie, and same could be said for Johnny Depp and Lawrence Fishburne in the Elm Street documentary "Never Sleep Again". For some reason these guys who go on to have big careers, or at least notable ones after they do horror movies don't ever care to talk about being in them. Kevin Bacon has hardly ever said anything about "Tremors" even though it's now a classic movie and his character was a big highlight of it.
