Factual error: In an attempt to create a believable 1940s gym, it appears the production crew got hold of many contemporary boxing posters as possible. Most of these were Greeked to avoid mentioning real boxers (such as "Dave Ritlaf" and "John Paropianeo"), but one of these prominently features a "Ronnie Harris", along with a photograph. Ronnie Harris was a real boxer, but wasn't even born until 1948, 7 years after this scene was set, giving away that a poster from the '70s was used. (00:16:08)
Raging Bull (1980)
1 factual error - chronological order
Directed by: Martin Scorsese
Starring: Robert De Niro, Joe Pesci, Cathy Moriarty, Frank Vincent
Visible crew/equipment: When Jake is in the bedroom with his wife (where he pours ice water on himself to calm down) you can see the top of some crew member's head in the foreground right below the camera lens.
Jake La Motta: Did Salvy fuck Vickie?
Joey LaMotta: What?
Jake La Motta: Did Salvy fuck Vickie?
Joey LaMotta: Jack. Jack, don't start your shit. I mean it, don't start.
Trivia: The film was amusingly satired by Mad Magazine as Raging Bully - truly an apt title.
Chosen answer: No. But Jake's paranoia and possessiveness had consumed him to such a degree that he was convinced that he (Joey) had, based on Vickie's impulsive remarks.
