ET hits the red carpet for producer Jerry Bruckheimer's new animated spy film 'G-Force' to get the inside scoop on the new film, as well as details into 'Iron Man 2' from actor Sam Rockwell and director Jon Favreau.

"It's a strange coincidence that we teamed up to do 'Iron Man' but it's a nice coincidence," Rockwell says of working with Favreau in both 'Iron Man' and 'G-Force.'

'G-Force' is a comedy adventure shot in Disney Digital 3D that tracks the evolution of a covert government program that trains guinea pigs to work as spies. "I talk to myself a lot so talking to an imaginary guinea pig was pretty easy," Zach Galifianakis tells ET of his role in the film.

The all-star cast includes Galifianakis, Will Arnett, Rockwell, Favreau, Nicolas Cage and Tracy Morgan. 'G-Force' hits theaters July 24.
