Gene Hackman was mentioned, who pretty much played the same guy in “The Conversation” (1974) and “Enemy of the State” (1994). The way he left us was tragic and odd, too.
Then we have the fictional threat of “Hail HYDRA” in so many Marvel movies. Good thing we don’t really have a secret government within the government; right?
Hold on; the dog is barking at the door...
“The Conversation” (1974)
Another very good one.
