The 1987 movie
- When Oscar charges into the fray against the gangsters on the bridge. For an accountant with a gun, he looked very badass.
- Odessa Steps homage scene. Also Pop-Cultural Osmosis - the average modern moviegoer will probably know this scene from The Untouchables rather than Battleship Potemkin.
- Ness' last words to Capone in the court room. After a scene with Capone declaring that a fight should be fought to the end to truly see the winner, Ness essentially turns his own words back on him, and caps it off with a positively epic "There endeth the lesson," line whilst grinning triumphantly at the mobster. Cue Capone needing to be held back by his entire crew.
- Ness throwing Nitti off the roof of the courthouse to his death while saying, "Did he sound anything like that?!"
- Jimmy Malone, a veteran, wise and tough street cop of Irish ancestry who is very pissed with Chicago's corruption and is portrayed by Sean Connery. Truly Oscar worthy.
Mobster: You got a warrant?Malone: Sure, here's my warrant. (Punch in the belly)
- Ness dealing with the corrupt alderman and his bribery.
- This theme courtesy of Ennio Morricone.
- Real Life example: Billy Drago, who portrayed Frank Nitti, recalled that while they were filming scenes on the streets of Chicago, he was told about a couple of teenage street gangs getting ready for a gang fight. At the request of the Chicago Police Department, Drago, wearing his costume and armed with his prop tommy gun, went to the place where the fight was supposed to happen. The gang members were in such awe of him that they didn't fight.
