Looking for Actors in all the (wrong TV) places

[Irene]

TV has been unsatisfying. I limit myself to Basic Cable. So lately I've been character hunting. 
Did you know that Bruce Campbell of all of those SF movies was in a Hallmark movie? "One December Night" had both Bruce and Peter Gallagher in the cast. 
Matthew Lewis, from the HP movies was in the first season of the re-make of "All Creatures Great and Small". That season also had Dame Diana Rigg. 

I watch the Father Brown Series for Mark Williams (also HP). William Shatner is doing a series on the History Chanel (and a guest visit to Oak Island).

Who have you spotted?

My wife has been watching Hallmark movies this season and she mentioned a couple of people but I don't recall whom.

I kind of started hunting for now-famous actors in their early films after reading about a couple I didn't recognize when I first saw the movies. Vin Diesel was in Saving Private Ryan, for example. He was Private Caparzo (in Tom Hanks' squad). He also played a hospital orderly in Robin Williams' Awakening.

I'm sure hardcore Diesel fans know that.

I also recently discovered that Nathan Fillion (Firefly, Serenity, Castle) had a small role in Saving Private Ryan.

Colin Ferguson (Eurika!) has done several Hallmark movies.

I suppose actors in SF "got-to-eat" and take rolls as they come

Just discovered (again, I suppose) that Peter Cullen (voice of Optimus Prime) was a skit actor on several 1970s comedy shows, including The Sonny and Cher Comedy Hour and The Hudson Brothers Razzle Dazzle Show. He also did announcer work for a number of shows.
