Last fall Activision hyped Call of Duty: Black Ops' upcoming release with a commercial starring Kobe Bryant and Jimmy Kimmel. They released another star-studded trailer today for Call of Duty: Modern Warfare 3 with Superbad's Jonah Hill and Avatar's Sam Worthington.

The video is called "The Vet & The n00b." Worthington is the seasoned pro while Jonah Hill is the greenhorn who doesn't watch out for mines and uses rocket launchers in close quarters. However, with a little trial and error, he finally learns the ropes.

A certain NBA star makes a cameo toward the end of the video. What's that, female reader? You scratched a Sam Worthington-sized hole in your screen and can't see who it is? Fine - it's Orlando Magic center Dwight Howard. Apparently he's a noobtuber.

Modern Warfare 3 launches on November 8th worldwide.
