Vince Vaughn and Jon Favreau - close friends and professional pals since Swingers - will team up for a new new movie called Couples Retreat.

The actors have appeared together briefly in the movie The Break-Up, and will do so again in and the upcoming Four Christmases, but this will mark their first true collaboration (that people will see, we don't count 2001's Made) since Swingers; Couples Retreat is based on an original idea from Vaughn himself.

According to Variety, the movie will follow four couples that go to a tropical island resort. While one pair is there to work on their marriage, the other is there for a good time. Comedy ensues.
