The series is executive produced by Stuart Krasnow ("The Weakest Link," "Average Joe") and Carlos Ortiz ("The Amazing Race"), who said they're able to cast the show with a wider net than when they work on commercial broadcast network shows.
"One of the best parts about the show is we don't have to go for specific look or over-the-top personalities," Ortiz said. "We are looking specifically for authenticity and diversity within the cast itself. We won't go for a bunch of claims about [descendants of] the Mayflower, we want to spread it out. We don't have to say, do they fit the looks bill? We're looking to see, do they fit the cool, authentic history bill? It's just one of those educational programs."
