Though he’s still a newcomer to the business, Narnia’s Will Poulter is still making waves, having just been cast alongside Jennifer Aniston and Jason Sudeikis in the pot comedy We’re the Millers.

The film stars Sudeikis as a “a veteran pot dealer who creates a fake family as part of his plan to move a huge shipment of weed into the U.S. from Mexico.” Aniston will play the the hooker pretending to be his wife while 19-year-old Poulter, who played the rambunctious yet good-hearted Eustace Scrubb in The Chronicles of Narnia: The Voyage of the Dawn Treader, will star as Kenny, a teenager who Sudeikis’ character pretends is his son. Poulter, whose last film was the Dexter Fletcher-directed indie drama Wild Bill, will begin shooting Millers on July 18.

Rawson Thurber (Dodgeball) directs the New Line comedy using a script by Steve Faber (Wedding Crashers) and Dan Fybel (The Sarah Silverman Program). Ed Helms is also set to star with Tucker Tooley, Vincent Newman, Happy Walters, and David Heyman as producers on the project. [Deadline]
