Will Poulter has signed up to star alongside Jennifer Aniston and Jason Sudeikis in big screen comedy We're The Millers.

The 19-year-old British actor - who has appeared in The Chronicles of Narnia: The Voyage of the Dawn Treader, Son of Rambow and Wild Bill - is due to start filming the stoner comedy with the Hollywood stars next month, Variety reports.

Jennifer will star as a prostitute, who pretends to be the wife of a drug dealer (played by Jason) so they can smuggle drugs across the country. Will will play their fake son.

The raunchy comedy, which is being described as a "warped vacation", has a script by Wedding Crashers writers Bob Fisher and Steve Faber, with Harry Potter's David Heyman as a producer alongside Happy Walters, Vince Newman and Tucker Tooley.

It will be directed by Dodgeball's Rawson Thurber.
