Avengers: Age of Ultron trailer has already been shown at the 2014 San Diego and New York Comic-Cons and ideally, the next step should be releasing it for fans and audience worldwide...which could happen tonight.

According to Moviepilot, a glimpse of Avengers: Age of Ultron might be revealed tonight (October 15) around 9.20 pm on Disney XD - the channel that airs all of the Marvel animated shows.

A few days back, Disney XD aired a special Avengers: Age of Ultron behind-the-scenes video (below) from the film's set.

Could the rumoured upcoming secret reveal be another such on-sets clip or will it be the official trailer?
