When can fans have a chance to see the first trailer of "Iron Man 3"? According to latest report, the much-awaited footage will allegedly be released for public sometime soon despite the fact that the third armored hero film itself is still far from hitting theaters everywhere.

Per Comic Book, Marvel indicates that it will debut "Iron Man 3" trailer in a foreseeable future after introducing the sneak peek to lucky fans in London on Thursday, September 13. During "The Avengers" Blu-Ray/DVD event at Disney offices in Hammersmith, fans were treated to a surprise extra bonus which turned out to be the "first ever showing" of the third "Iron Man" flick.

Lucky fans who have watched the footage described it as "being similar to the Iron Man 3 footage shown at Comic-Con but a little bit different." Apparently, it didn't show the rumored description of the first "Iron Man 3" trailer which made its round onto the web recently.

According to sources, the trailer shown in London unveiled the first look at Ben Kingsley as The Mandarin. It also showed "Tony Stark's Malibu mansion getting blown up, and the Iron Man extremis suit." Attendees additionally said the footage was "mind blowing, very dark and amazing."

To be released in the U.S. on May 3, 2013, "Iron Man 3" reportedly will be loosely based on Warren Ellis' six-issue "Extremis" comic book series, which presents a new origin story that focuses on nanotechnology. Robert Downey Jr. will return as Tony Stark a.k.a the titular superhero.
