Twin Versus Twin

OK, so this is going back to television. The idea is for a fictional narrative that follows the format of a reality TV program. The premise is that in every set of twins there is an evil twin. So this show groups 10 sets of twins on an island in the middle of the Pacific, they have 8 weeks to prove that they are the non-evil twin because each non-evil twin wins $25,000. BUT, somewhere during the first week there are sightings of other people on the island. Eventually it comes out that this is the second time that they have tried to film this reality TV but the first time all the evil twins killed everyone, because they are evil. Now there are 20 evil twins, 10 non-evil twins, and a camera crew locked in an all out battle for survival. I was going to call it like Survival, or Surviving or something.... but then I realized Twin Versus Twin was a way more realistic name for a reality TV show.
