Brooklyn Nine-Nine first look: Lin-Manuel Miranda to play Amy's brother

Brooklyn Nine-Nine is bringing Lin-Manuel Miranda into the family, and Amy Santiago is about to say, “Oh, brother!”

NBC’s police comedy will feature the Hamilton mastermind as a guest star in the March 7 episode, titled “The Golden Child,” EW has learned. Miranda, who recently starred in Mary Poppins Returns, will play David Santiago, brother of Amy (Melissa Fumero) and her rival. Miranda has loudly voiced his love for the beloved comedy, tweeting his support for the show (see below) right after it was canceled by Fox earlier this year after five seasons. NBC swooped in quickly and picked up the show for a 13-episode sixth season, and later added five extra episodes.

Miranda was one of several celebrity fans to take to social media and rally behind the show in its time of need, joining Mark Hamill, Sean Astin, and Patton Oswalt (who had previously appeared on the series). Asked in May if he envisioned some of these famous fans popping up on the show, co-creator Dan Goor told EW, “We’re huge fans of all of those actors. And we’d love to try to figure out ways to put them on our world.”

Miranda, who is friends with Fumero, celebrated with the cast when NBC announced its rescue of Brooklyn. He guest-starred last season in two episodes of Curb Your Enthusiasm and lent his voice to three episodes of DuckTales. Miranda recently reprised his lead role in Hamilton for a three-week run of the production in Puerto Rico to raise money for artists struggling in the aftermath of Hurricane Maria.

Brooklyn Nine-Nine airs Thursdays at 9 p.m. ET.
