Explosions, rain, people running about screaming and cars crashing into each other; that’s what promises to be in store for anyone planning on watching Iron Man 3 when it comes out, if these Youtube clips of the filming are anything to go by.

We’re sure that there’s going to be plenty more to the finished film in fairness, but the bulk of these videos – taken by various onlookers when filming was taking place in Hollywood last night (January 21, 2013) – are showing basic action scenes, with none of the cast clear in any of the shots. These aren’t really spoilers because they don’t really show much of an insight into the story, but it is fascinating to watch nonetheless, giving an insight into the scale that goes into such high-budget action films. Honestly, some of the explosions are dead loud. Bleeding Cool has collected a few of the best clips, whilst you can see a couple below.

Elsewhere – and in something that perhaps reveals more of the plot than these videos – producer Kevin Feige has told MTV that the film will find Robert Downey Jr’s Tony Stark character in a state of “post-traumatic stress”. The film is set post The Avengers and sees Stark trying to cope with a new-found feeling of weakness. "It's almost like post-traumatic stress [disorder]” Feige said. “He has retreated after the events of The Avengers into his workshop, where he's building advanced versions of his suits. He has [designed] a version of the suit that can latch onto him in individual pieces, any time, anywhere. He starts to realize [that] he doesn't want to be out of the suit."

There has been a trailer already out for Iron Man 3, featuring a glimpse of Ben Kingsley in his impressive-looking role as The Mandarin. See it below.
