Inspired by this thread, I was thinking about supporting cast members who seem to pop up together a lot. In that thread, it was noted that Vince D’Onofrio and Vince Vaughn seem to work together quite a bit.
One example is Steve Buscemi and Shawnee Smith- she was his bar date at the beginning of Armageddon and his live-in girlfriend in The Island.
Another was the Aliens crew (Paxton, Henricksen, Goldstein)- all of them were also seen in Near Dark and a couple of other films together.
Who else seem to pop up in the same movies a lot?
