The first trailer for the raunchy, R-rated comedy 21 and Over starring Twilight‘s Justin Chon and from the writers of The Hangover has been released, giving a good glimpse at the gags we can expect from the film.

What looks kind of like The Hangover meets Project X, 21 and Over tells the story of a promising student who celebrates his 21st birthday with his two best friends the night before his big medical school exam. So swap 21st birthday with bachelor party and swap medical school exam with wedding, and things get very familiar.

Take a look at the trailer below:

Written and directed by Jon Lucas and Scott Moore (The Hangover writers), 21 and Over stars Justin Chon (Twilight), Miles Teller (Rabbit Hole), Skylar Austin (Pitch Perfect) and Jonathan Keltz (Prom). While The Hangover connection will probably get people into the theaters, it will be interesting to see how this one fares considering the obvious connections. 21 and Over is headed for a March 1, 2013 release from Relativity Media.
