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.

Elliot Ness: I have one more thing to say. I know that many of you take a drink. What you've done before today is not my concern. But now we must be pure and I want you to stop. It's not a question of whether or not it's a harmless drink, it may very well be, but it's against the law, gentlemen, and as we are going to enforce the law, we must do first by example.

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.

Question: In the scene where Malone is shot by Nitti, he crawls to a room and when Ness comes in he finally gets Ness to see the paper about the man coming into the train station. If that information was so vital why was he just roaming around his apartment instead of going to Ness to show him?
