Samuel L. Jackson and Paul Giamatti both have form on animated movies, Jackson on the likes of The Incredibles and Giamatti in Robots and The Ant Bully, and now they’re going CG again as THR reports they’ve joined the voice cast of Dreamworks Animation’s Turbo.

The animated film follows an ordinary garden snail with an impossible dream to become the fastest snail in the world. His obsession with speed and all things fast has made him an oddity and outsider in the slow and cautious snail community, and a constant embarrassment to his careful older brother. When he is one day imbued with the power of amazing speed, he embarks on a quest that will see him racing in the Indianapolis 500.

Also signing up are Michael Peña, Luis Guzmán, Bill Hader, Richard Jenkins, Ken Jeong, Michelle Rodriguez, Maya Rudolph, Ben Schwartz, Kurtwood Smith and Snoop Dogg, who join the previously cast Ryan Reynolds, who’ll voice the main character. David Soren is directing and writing from his own original concept, with the movie due out July, 2013.
