‘Brooklyn Nine-Nine’ Superfan Lin-Manuel Miranda to Guest Star on ‘Brooklyn Nine-Nine’

”Hamilton“ creator — who helped save the series after Fox cancellation — will play Amy’s brother

Lin-Manuel Miranda is taking his obsessive love for “Brooklyn Nine-Nine” from his personal life to his professional life, as the “Hamilton” creator will guest star on an upcoming episode of the now-NBC comedy, TheWrap has learned.

Miranda will appear on the March 7 installment, titled “The Golden Child,” as David Santiago, one of Amy’s (Melissa Fumero) brothers, who she considers a rival.

The “Mary Poppins Returns” star is a self-professed superfan of the Dan Goor-created comedy, who loudly voiced his support for the show on Twitter when it was canceled by Fox last May after a five-season run.

The series was saved by NBC just one day later, with Goor and “Brooklyn Nine-Nine” star Andy Samberg crediting the quick revival to the outcry on social media from both everyday fans and celebs like Miranda, Seth Meyers, Mark Hamill, Guillermo del Toro and Sean Astin — who they have dubbed the “Guardians of the Nine-Nine.”

“Brooklyn Nine-Nine” premiered on its new network last month, with its currently-airing sixth season set to include 18 episodes (upped from an initial 13-episode order from NBC). Series regular Chelsea Peretti exited the show on Season 6’s fourth episode, which aired Jan. 31.

“Brooklyn Nine-Nine” airs Thursdays at 9/8c on NBC.
