MTV’s “Catfish” never had an episode with the drama that surrounded former Notre Dame football standout Manti Te’o, the Hawaiian-born linebacker infamously duped into believing his longtime girlfriend, whom he never met in person, died just ahead of the 2013 BCS National Championship Game. It was a tabloid story that left many wanting the real truth, but it took Chapman and Maclain Way’s Netflix documentary series “Untold” to reveal it. “It’s obviously been a white whale in the sports world,” Chapman told IndieWire of the Manti episode, “The Girlfriend Who Didn’t Exist.” The Ways, with directors Ryan Duffy and Tony Vainuku, captured a many-hours-long interview with the former linebacker (and many more hours with his catfisher).
