Jennifer Aniston and Jason Sudeikis let the R-rated language fly during their introduction for the second We're the Millers red band trailer. The stars play a fake couple who, along with their pretend children (Emma Roberts and Will Poulter) go on a road trip to smuggle an RV full of marijuana back from Mexico. As you can see in this footage, not everything goes according to plan in this comedy from director Rawson Marshall Thurber, in theaters August 7.
