The first trailer of the Michael Bay-produced “Teenage Mutant Ninja Turtles” has been made available online after it premiered at the CinemaCon in Las Vegas earlier this week.

The reboot, set in New York City, shows Shredder and his evil Foot Clan have an iron grip on everyone from the police to the politicians. The video shows the first encounter between April O’Neil and one of the turtles. The trailer also reveals the connection between April’s father and Shredder.

"Crime, violence and fear have run rampant. Our great state is being destroyed. People want justice restored to this world. People want heroes, Ms. O'Neil," says the Shredder, in the trailer. "Heroes are not born, they're created. That was what your father and I were trying to do. Create heroes."

Bay’s motion-capture CGI turtles are voiced by Pete Ploszek for Leonardo; Noel Fisher for Michelangelo; Alan Ritchson for Raphael; and Jeremy Howard for Donatello. William Fichtner plays the bad guy, Shredder, and Megan Fox portrays April, the human who later befriends the four Ninja Turtles.

On Thursday, Will Arnett, who plays Vernon Fenwick in the film, went on NBC's "Today" to promote the film and unveiled the first glimpse of the trailer.

"I brought some pizza. My buddies, the Turtles, it's their favorite thing to eat. I don't know if people knew that," he said on the show.

The movie is directed by Jonathan Liebesman and is slated for an Aug. 8 release.
