‘The Challenge’ Season 37: Meet the Cast of ‘Spies, Lies and Allies’ (PHOTOS)

MTV’s The Challenge is bringing in challengers from around the world for its upcoming 37th season.

Spies, Lies and Allies, filmed in Croatia and premiering on Wednesday, August 11 at 8/7c, will feature 17 “international players alongside “elite U.S. agents.” In 19 episodes, these 34 challengers will be tested mentally and physically as they compete in hopes of walking away with their share of $1 million. On Monday, August 9 at 8/7c, a launch special — The Challenge Spies, Lies and Allies: Global Activation — will offer fans a sneak peek and introduce the cast.

Among the veterans (anyone who’s done a Challenge before) returning are CT Tamburello (one of the winners of Season 36, Double Agents), Aneesa Ferreira, Nany Gonzalez, and Cory Wharton. The rookies come from versions of Survivor, Big Brother Nigeria, Love Island, 12 Dates of Christmas, and other reality shows. Scroll down to get to know the 34 players.

Watch the trailer below for a look at the cast, some of the daily challenges, the vets’ super-alliance, the hookups, injuries, and more. Of course, it’s going to be a dirty game. As TJ tells them, “the twists keep coming” — including an additional player showing up.
