To say Jake Gyllenhaal will surprise you with his singing is an understatement because he can SING.

Gyllenhaal recruited 'True Detective' director Cary Joji Fukunaga to helm the camera in this one-take of his performance of 'Finishing The Hat' from 'Sunday in the Park with George', the musical he's set to make his debut in this month.

"This is what happens when Riva Marker (the badass president of NineStories) and I invite Cary Joji Fukunaga to rehearsals for our new Broadway musical. Check out this video we made! #SundayintheParkWithGeorge," he wrote in a Facebook post which accompanied the video.

The video follows Gyllenhaal as he moves down through the theatre accompanied by an orchestra during a rehearsal and looks like it could easily be an outtake of 'La La Land' or 'Birdman'.

Which is why there needs to be a petition for a Cary Fukunaga-directed musical starring Gyllenhaal for us to sign ASAP.
