If being adorable was a weapon, then the monsters in the new Monsters Vs. Aliens trailer would win, hands down. Especially since they include Insectasaurus, the 350-foot tall baby grub that's teething on skyscrapers. This new Dreamworks CG feature, coming next March, shows America pulling together its secret monster defense team, made up of Ginormica aka Susan (Reese Witherspoon), B.O.B. (Seth Rogen) and The Missing Link (Will Arnett). The new trailer explains each characters' superpower and how it relates to the U.S., but hopefully the movie will explain why America is the only place getting attacked by those freedom-hating aliens.
