Musical episodes are TV treats that don't happen often enough.
There's the classic "Once More With Feeling" episode of Buffy, the Vampire Slayer and even shows like Ally McBeal, How I Met Your Mother and 30 Rock had their characters break into musical numbers now and then.
Now Mindhunter, Netflix's new series about serial killers, might not seem like an obvious choice for a musical adaptation but think about it: The series stars Jonathan Groff, who is known for his roles on Broadway in Hamilton and Spring Awakening, and the show's executive producer—and sometimes director—is David Fincher, who got his start directing iconic music videos for Madonna and Bjork.
When Groff swung by The Late Show with Stephen Colbert this week he revealed Fincher told him how he wanted to get into directing musical theater, so naturally Colbert's team of writers created "Mindhunter: The Musical" for Groff to serenade the audience with a song about serial killers.
"I hunt minds of men who won't atone, but way down deep within me, though killers want to skin me, the mind I'm really hunting is my own," Groff sang during his "impromptu" musical number.
With Groff being a Broadway baby—even his Mindhunter co-star Anna Torv is no stranger to TV musical episodes—we think "Mindhunter: The Musical" is only a matter of time.
