HBO has just released a teaser for its new dark comedy, Barry, starring Bill Hader.

Hader is known for his hilarious work as a cast member on Saturday Night Live and the handful of roles he's taken in movies and TV shows.

His brilliant work always left audiences wanting more, and, with Barry, it looks like HBO is going to deliver just that. The eerie, uncomfortably funny, California-based trailer introduces us to Hader's title character who is a "world-class" assassin who becomes engrossed in the Hollywood acting world.

Check out the trailer below:
