It’s a problem many big action spectaculars face – you want the main star to do as many of the stunts as possible, so that it’s clearly them doing it on screen, but you always run the risk of them injuring themselves. That’s the issue Iron Man 3 has faced, as production was temporarily shut down after star Robert Downey Jr. was injured on the set.

Marvel Studios released the following statement regarding the unfortunate incident, ‘Robert Downey Jr. sustained an ankle injury on the set of Iron Man 3 in Wilmington, North Carolina while performing a stunt. There will be a short delay in the production schedule while he recuperates.’

There are no specifics on what kind of ankle injury he sustained, although it does not seem to be serious. There’s also no news on how long things will have to shut down for. However it doesn’t appear this will affect the release date. Production began in early June, with Shane Black directing from a screenplay he co-wrote with Drew Pearce.

Iron Man 3 has started shooting, and to prove it Marvel has released the picture above of Robert Downey Jr. on set, in front of a line-up of his super-powered suits, just ready to appear in a shot.

Here’s the US press release that accompanied the image: BURBANK, Calif. (June 4, 2012) – Following in the footsteps of the record-breaking Marvel Studios’ release “Marvel’s The Avengers,” production on the highly anticipated film “Iron Man 3,” directed by Shane Black, has commenced production in Wilmington, North Carolina. The production schedule will also include locations in Raleigh/Durham, North Carolina, Miami, Florida and China.

Based on the ever-popular Marvel comic book series, first published in 1963, “Iron Man 3” returns Robert Downey Jr. (“Iron Man,” “Marvel’s The Avengers”) as the iconic Super Hero character Tony Stark/Iron Man along with Gwyneth Paltrow (“Iron Man,” “Iron Man 2,”) as Pepper Potts, Don Cheadle (“Iron Man 2”) as James “Rhodey” Rhodes and Jon Favreau (“Iron Man,” “Iron Man 2”) as Happy Hogan. Set for release in the U.S. on May 3, 2013, Marvel’s “Iron Man 3” marks the second feature to be fully owned, marketed and distributed by Disney, which acquired Marvel in 2009.

“Iron Man 3” continues the epic, big-screen adventures of the world’s favorite billionaire inventor/Super Hero, Tony Stark aka “Iron Man.” Marvel Studios’ President Kevin Feige is producing the film. Executive producers on the project include Jon Favreau, Louis D’Esposito, Alan Fine, Stan Lee, Charles Newirth, Victoria Alonso, Stephen Broussard and Dan Mintz.

The creative production team on the film includes two-time Oscar®-winning director of photography John Toll, ASC (“Braveheart,” “Legends of the Fall”), production designer Bill Brzeski (“The Hangover,” “Due Date”), editors Jeffrey Ford, A.C.E. (“Marvel’s The Avengers,” “Captain America: The First Avenger”) and Peter S. Elliot (“Fantastic 4: Rise of the Silver Surfer”), and costume designer Louise Frogley (“Quantum of Solace,” “Contagion”).

Marvel Studios most recently produced the critically acclaimed “Marvel’s The Avengers,” which set the all-time, domestic 3-day weekend box office record at $207.4 million. The film, which is currently in release, continues to shatter box office records and is The Walt Disney Studios’ highest-grossing global and domestic release of all time and marks the studios’ fifth film to gross more than $1 billion worldwide.

In the summer of 2011, Marvel successfully launched two new franchises with “Thor,” starring Chris Hemsworth, and “Captain America: The First Avenger,” starring Chris Evans. Both films opened #1 at the box office and have grossed over $800 million worldwide combined. In 2010 “Iron Man 2,” starring Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, Scarlett Johansson and Mickey Rourke, took the #1 spot in its first weekend with a domestic box office gross of $128.1 million.

In the summer of 2008, Marvel produced the summer blockbuster movies “Iron Man” and “The Incredible Hulk.” “Iron Man,” in which Robert Downey Jr. originally dons the Super Hero’s powerful armor and stars alongside co-stars Terrence Howard, Jeff Bridges and Gwyneth Paltrow, was released May 2, 2008, and was an immediate box office success. Garnering the number one position for two weeks in a row, the film brought in over $100 million in its opening weekend. On June 13, 2008, Marvel released “The Incredible Hulk,” marking its second number one opener of that summer.
