This film turned out to be amazing, but fans' doubt that Joss Whedon would be able to pull it off was destroyed at the release of this superbowl trailer. The line "we're not a team...we're a timebomb" sends a shiver down my spine watching the trailer, but was slightly altered and,in my opinion, ruined in the movie.

Released between the disappointing teaser and the over-long third trailer, this was a perfect mix of disturbing, quiet moments and loud bangs. I have watched it numerous times, mostly trying to identify Hypable's John Thrasher in the corwd at the football game.

The film was only OK, but this exciting and gripping 90 second thrill ride, featuring a super-cool rendition of 'Immigrant Song' by Karen O and Trent Reznor (coming off an Oscar nomination for 'The Social Network) was by far one of the very best trailers of 2011.

Released just days after the film's 8-month delay was announced, this beautifully designed teaser got fans really excited for, in my opinion, one of the best 'Potters'
