The first trailer for Michael Bay's live-action Teenage Mutant Ninja Turtles film debuted Wednesday night at CinemaCon in Las Vegas, and despite all the negative comments from fans and critics, the movie actually looks promising.

The 80-second trailer finally reveals what the CGI turtles look like (which is pretty much exactly what you'd imagine a CGI mutant ninja turtle in a live-action film would look like) and reveals a few changes to the turtles' origin story.

William Fichtner, who plays number-one TMNT villain Shredder, reveals that he and the father of news reporter April O'Neil (Megan Fox) had something to do with how the turtles were created.

"His connection and relationship to the turtles is a bit surprising and for an actor playing it, the back story, which comes out in this film, is really intriguing," Fichtner said in an October interview with website Flicks and the City. "We made some changes while filming that I thought are just awesome."

Little action is revealed in the trailer other than a subway scene where numerous bad guys (Shredder's Foot Clan, we presume) get taken out by something much too fast to see, while April shoots video of the melee on her phone. Shortly after, two of the turtles are seen sliding down a snow-covered mountain and one flings the other into the side of an army vehicle to destroy it.

April finally meets the turtles for the first time on a rooftop when leader Leonardo and joker Michelangelo swoop in, and the latter provides the typical TMNT brand of humor while attempting to calm her down.

"Teenage Mutant Ninja Turtles" is set to open on August 8.
