Corrected entry: Sgt Trapp in a conversation utters the rebuke "Cluster-fuck." This didn't get used until twenty years later when it was spoken first by Malcolm Tucker in the fictional BBC-TV political show "In The Thick Of It"
BlacKkKlansman (2018)
1 corrected entry
Directed by: Spike Lee
Starring: Alec Baldwin, Robert John Burke, Isiah Whitlock Jr., John David Washington
Factual error: At the David Duke meeting, a Klansman is told to take an urgent call on the phone and goes outside to take it. The grey telephone is a British 1970's one, not an American one.
David Duke: America first.
Klansmen: America first. America first.
Waiter: If I would have known that this was a Klan meeting, I wouldn't have taken this motherfucking gig. Shit.
Correction: It's been used since at least the Vietnam war.
