The newest TV spot for the 'Teenage Mutant Ninja Turtles' movie has debuted, offering a brief, but revealing look at the characters in the film.

The TV spot, uploaded by IGN, may only last for 30 seconds, but we're shown quick snippets of new characters that haven't been seen in the first live action trailer for the Michael Bay-produced, Jonathan Liebesman-directed movie, which lasted for about a minute more.

If you've got keen eyes and fast reflexes, you can pause during the TV spot to catch glimpses of Master Splinter brandishing a katana and Will Arnett's Vernon Fenwick clutching a shocked April O'Neil, played by Megan Fox.

Other than the new character reveals, most of the footage is recycled from the previous trailer, including the bit in which Donatello launches himself shell-first into Hummer. But there are a few new action shots that include a turbo-powered skateboard, some S.W.A.T. teams, collapsing buildings and some relatively tame fight sequences.

Expect to see the heroes in a half-shell in theaters on Aug. 18.
