- Americans Hate Tingle: The film was a major box office success in the US and won the Academy Award for Best Picture but was not well-liked in Canada due to the large number of inaccuracies made to the story to make the Americans out to be the sole heroes of the rescue (according to the former Canadian ambassador to Iran Ken Taylor, who was involved with the actual rescue, the Americans only did about 10% of the work while Canada handled the lion's share of what went on). The film even got such a poor reception at the Toronto Film Festival that director Ben Affleck had to go back and recut some of the film (less than a month before opening) to give a fairer portrayal of the Canadians.
- Iran also expressed anger at the film winning an award, though considering the subject matter that's not really a surprise.
- Award Snub: Ben Affleck wasn't even nominated for Best Director at the Oscars. What's extremely jarring is the fact that Affleck completed a sweep of the top prizes of all of the season's major precursor awards: he won the Critics' Choice Award for best picture (and best director), the Golden Globe Award for best picture-drama (and best director), the Producers Guild of America Award for best produced picture, the Screen Actors Guild Award for best ensemble, the Directors Guild of America Award for best director and the BAFTA Award for Best Film and Best Director. All these wins were supposed to position Affleck as the favorite for the Best Picture and Best Director Oscar (and Argo won the former) and yet he didn't even receive an Oscar nomination for Best Director. Even Oscars host Seth MacFarlane made a joke about it during the ceremony: "Argo tells the previously classified story about an American hostage rescue in post-revolutionary Iran. The story was so top secret that the film’s director is unknown to the Academy."
- The film's Best Picture win marks the first time since 1989, when Driving Miss Daisy won top honors, that the director of the Best Picture winner wasn't nominated for Best Director. Though it was much less egregious in that case because Bruce Beresford hadn't won any awards for directing it and in fact was barely nominated for anything at all. And the fact that Driving Miss Daisy became an unpopular choice for Best Picture fairly quickly afterwards (having beat out My Left Foot and Born on the Fourth of July, as well as the un-nominated Do the Right Thing) makes it less of a snub.
- At the very least, since Affleck was also one of the producers of the movie, he still managed to win an Oscar for his work on the film, even delivering the speech to close the night.
- Retroactive Recognition: Taylor Schilling, who appears very briefly as Tony Mendez's wife, would go on to gain great acclaim as the lead of Netflix's Orange Is The New Black.
