The Untouchables (1987)

Factual error: In the warehouse scene with the wooden crates with maple leaves, even though a correction has been submitted saying a maple leaf was valid, the real mistake is the type of maple leaf used. The film shows a modern graphic style of leaf that did not come into use until the 1960s and appeared on the new Canadian flag in 1965. In the time of Capone, the maple leaves used to depict things Canadian looked like actual maple leaves and not like a stylized graphic.

Jimmy Malone: He pulls a knife, you pull a gun. He sends one of yours to the hospital, you send one of his to the morgue. That's the Chicago way!

Trivia: As the stroller is going down the stairs in the train station it is a reference to the staircase scene in "Battleship Potemkin" in which a stroller similarly falls down a flight of steps while the horrified mother looks on.
