List your favourite character actors (and a film people would know them from)

Not to mention Calvera in The Magnificent Seven.

It amazing how he seems to play every major character’s father, including being the dead father in Six Feet Under. A lot in common with William Schallert, Patty Duke’s dad.

Was also Kevin Costner’s catcher in For the Love of the Game, a rather glurgy romance/baseball flick that I still inexplicably watch on occasion.

I have always loved Wilfred Brimley. Always the good-natured old coot. I remember him best as the crusty U.S. Attorney near the end of Absence of Malice.

Philip Baker Hall was one of P. T. Anderson’s main go-to guys from way back, having appeared in Magnolia, Boogie Nights, and Sydney/Hard Eight (in which he stars, actually).

Most people will probably remember him best as Mr. Bookman, the library cop, from an episode of Seinfeld.
ETA:

Not always so good-natured. Cf. The China Syndrome and The Firm.

Not to mention The Thing, one of the few films I recall that had him without his trademark walrus moustache

Yes, I’ll watch anything with Frank Morgan in it.
