The trailer for Couples Retreat is online. The comedy has a pretty good cast including, Jon Favreau, Vince Vaughn and Kirsten Davis.

Four couples head to a retreat where one of them wants to work on their marriage. The others aren't so interested though.

Jon Favreau, Vince Vaughn, Malin Ackerman, Kirsten Davis and Jason Bateman are amoung the stars of Couples Retreat. When one couple decide they are going to a tropical island to attend a couples retreat, their friends decide to join them. Thinking that they can just enjoy the surroundings, and not partake in any couples therapy. Turns out the therapy sessions aren't optional though.

The trailer is below from Jo Blo. And you can also see it in HD on Apple. The trailer looks okay, not side splitting funny though. Take a look and see what you think.
