Editor's Note: AMC has been wrong in the past and simply used assumed runtimes before (such as initially listing The Amazing Spider-Man at 90 minutes) until official confirmation was obtained. The 2 hr 9 minute runtime originates from IMDB which is hit or miss (at best).
Iron Man 3 is due to hit on May 3rd and the run time for the length of the movie looks to have become known coming in and revealed by AMC Theaters to run at 2 hours and 9 minutes.
Marvel Studios’ Iron Man 3 pits brash-but-brilliant industrialist Tony Stark/Iron Man against an enemy whose reach knows no bounds. When Stark finds his personal world destroyed at his enemy’s hands, he embarks on a harrowing quest to find those responsible. This journey, at every turn, will test his mettle. With his back against the wall, Stark is left to survive by his own devices, relying on his ingenuity and instincts to protect those closest to him. As he fights his way back, Stark discovers the answer to the question that has secretly haunted him: does the man make the suit or does the suit make the man?
