Super Bowl viewers caught a slightly meatier glimpse of the upcoming Avatar: The Last Airbender than was offered by last summer's teaser trailer, and now Yahoo! Movies is sharing a brand-new, two-minute trailer that builds on that ad (watch it after the jump). The promo for the M. Night Shyamalan flick stresses the martial arts and special effects that promise to be the foundation of the movie.

Based on the defunct kids' cartoon (and now sans the "Avatar" part), The Last Airbender looks to be a desperate career-saving change for Shyamalan, who hasn't exactly made his name on family-friendly epics full of CGI tornados and magical, flying bison. But the trailer has spirit, even if it seems to take itself awfully seriously -- one of the things that made the cartoon Airbender so watchable was the show's smart humor, and the relationships between the characters. The new trailer, thankfully, gives those unfamiliar with the original material a chance to see who these characters are, and get an idea of the premise.

James Newton Howard is scoring the film, raising the question if the small sample used in the trailer is representative of what we can expect or if Howard's final version in July will sound much different from the sweeping, percussive track we have here (and if it's swiped wholesale from another film, like trailer-cutters tend to do, please share in the comments). The trailer's tone, music and effects are all pretty impressive, and this is the first time that a lot of us can allow ourselves to think that, just maybe, The Last Airbender could be pretty damn good.

The Last Airbender stars Noah Ringer, Nicole Peltz, Jackson Rathbone, Dev Patel and Aasif Mandvi and is scheduled to hit theaters on July 2nd.
