Robert Downey Jr. is no Tony Stark. According to Marvel Studios, the 47-year-old funny man injured his ankle on-set of the much-anticipated blockbuster "Iron Man 3" in Wilmington, North Carolina -- while performing one of his gravity-defying stunt. Production for the film, which began shooting in May, has been "slightly delayed" while the star recuperates.

Downey Jr. will undoubtedly do his best for a speedy recovery as to not disappoint the immense vision of director, Shane Black. "The way to go about doing a [third film] is you have to find a way the first two aren't done yet," he told MTV at this year's Comic-Con convention. "By the time you finish three, you want something resembling the culmination of a trilogy. I think we're finding ways of making this organic and new based on what's happened before ... Robert refers to it as leaving it all on the field. That's what we're aiming to do."

Downey's expectations for the upcoming film is likewise ambitious, no doubt he's hoping to surpass the last film's $623 million dollar success at the box office. "We realized at the beginning of 'Iron Man 2,' he's dying and he goes and has a party, so some [fans] didn't like him," he said. "There's a way to enjoy all that shadowy stuff. So we kept thinking about, 'What is it like if this guy is in this country? Where else could he go?'"

The movie is set to hit theaters on May 3, 2013, and actress Gwyneth Paltrow will reprise her role as Virginia "Pepper" Potts -- Tony Stark's love interest. New cast members include Ben Kingsley, Rebecca Hall and Guy Pearce.
