Jean Reno is the latest to join the cast of Peter Billingsley’s upcoming comedy “Couples Retreat,” according to the Hollywood Reporter.

Written by Jon Favreau, the film follows four couples who spend some time at a tropical island resort, where they quickly find out that participation in a couple therapy program is mandatory.

Reno is set to play a therapist and the owner of the resort. Vince Vaughn, Jon Favreau, Jason Bateman and Faizon Love play the guys, with Kristen Bell, Malin Akerman and Kristin Davis on board as the girls.

Reno, who recently starred in Eric Besnard’s “Ca$h,” will also appear in Harald Zwart’s upcoming sequel “Pink Panther 2.” He also recently wrapped filming for Nimród Antal’s “Armored.”

Final word: Reno as a crazy therapist in an American flick sounds totally hilarious. He alone will be worth seeing this.
