Skylar Astin and Justin Chon are in talks to join Relativity Media and Mandeville Films' comedy 21 and Over, starring opposite Miles Teller.

The Hangover writers Jon Lucas and Scott Moore are writing and directing the film, which follows two childhood friends who drag their straight-arrow buddy out to celebrate his 21st birthday the night before an all-important med school interview. As one beer leads to another, the evening spirals into an epic misadventure of debauchery and mayhem.

Skylar Astin and Miles Teller will play the hard-partying pals, while Justin Chon will play their perpetually anxious friend.

Production is slated to start production later this summer.
