If you missed Disney's fan event D23 last weekend (which we recapped here), you're in luck!  A number of the presentations have been made available online in short video clips.  Unfortunately, there will be none of the sneak-peek footage that was screened at D23, but you can take a look at the special guests and actors that showed up to talk about their upcoming movies.  Marvel's slate of films includes Thor: The Dark World, Captain America: The Winter Soldier and Guardians of the Galaxy.  Hit the jump to watch these D23 presentations and find out where you can view many more.
