Plot hole: How come the Extremis serum was able to regenerate Ellen Brandt's arm but not repair the scar on her face? According to the movie, the serum is supposed to rewrite the body's genetic code and constantly repair damaged cells, so her face should have been restored to its original state, just like her missing arm. Even if she had been born with the scar the serum would have healed it, just like it healed all of Aldrich Killian's physical impairments. (00:51:40)
Iron Man 3 (2013)
1 plot hole - chronological order
Directed by: Shane Black
Starring: Robert Downey Jr., Ben Kingsley, Gwyneth Paltrow, Guy Pearce, Don Cheadle, Rebecca Hall
Character mistake: When Harley asks Tony what the light is coming from his chest, Tony responds "an electromagnet." Harley replies "What does it power?" An electromagnet is not a source of power. The arc reactor is the power source which powers both the electromagnet (to keep Tony safe from the shrapnel near his heart) and the Iron Man suit. (00:43:25)
Tony Stark: I've dated hotter chicks then you.
Ellen Brandt: That's all you got? A cheap trick and a cheesy one-liner?
Tony Stark: Sweetheart, that could be the name of my autobiography.
Trivia: Once again, Stan Lee makes his usual cameo. This time, he appears as a judge at the Christmas pageant. (01:03:50)
Question: Is this movie set in December 2012, six months after the events of The Avengers movie, or December 2013? The newspaper handed to Tony in the garage is dated December 24, 2013.
Chosen answer: Iron Man 3 is set in December 2013, but at no point in The Avengers that I can recall was it ever stated to be 2012; that's just the year it came out, not necessarily the year it was set, so in-film continuity would suggest the Avengers is set in 2013.
Answer: With the release of Endgame, it is now fact that the Battle of New York took place in 2012.
