If you are a fan of ‘Survivor’ here is the video of all previous cast members that will participate in: “SURVIVOR: HEROES VS. VILLAINS” (video)

These unforgettable castaways will compete deep in the South Pacific on the breathtaking island of Samoa and will be divided into two tribes of 10 comprised of the best HEROES and biggest VILLAINS ever to play the game.  The HEROES have been defined by their decisions of integrity, courage and honor, while the VILLAINS have mastered their skills of deception, manipulation and duplicity.  
The series will follow the relationships and conflicts that develop among the two divergent groups.  Ultimately some castaways will be forced to choose between pre-existing relationships or tribe loyalty in the spirit of competition.  What happens on a tribe full of HEROES?  Will the VILLAINS self-destruct or will they be able to co-exist?
