Gary Oldman was a fantastic farting Oscar the Grouch in Slow Horses!

Also The Americans, The Diplomat, and The Man in the High Castle.

You get to see Keri Russel as a bad assed deep undercover sleeper agent Soviet spy in The Americans, Hal Wyler as an evil American Nazi dictator in The Man in the High Castle, and in The Diplomat they're a married couple of bad assed morally troubled patriotic ambassadors.
