Lin-Manuel Miranda is freestylin’…

The official trailer has been released for We Are Freestyle Love Supreme, the documentary about the 40-year-old’s improv hip-hop project.

Before Miranda’s Tony Award-winning musicals Hamilton and In The Heights, the Mary Poppins Returns star, Christopher Jackson, Thomas Kail and Anthony Veneziale, among others, traded off-the-cuff rhymes the way Second City actors swapped jokes in their improv hip-hop group.

Created by Miranda, Kail and Veneziale in the summer of 2005, its beginnings on sidewalks and a small performing space at New York’s Drama Book Shop, the show would make the rounds Off Broadway, ever-changing, before landing on Broadway for an acclaimed and commercial successful run last year.

The show’s long journey is chronicled in filmmaker Andrew Fried’s documentaryWe Are Freestyle Love Supreme, premiering on Hulu on Friday, June 5. Fried’s camera captures the group reuniting for a series of shows in New York City that led to the Broadway engagement.

Appearing in the doc, which debuted at this year’s Sundance Film Festival, are Miranda, Veneziale, Jackson, Kail, Arthur Lewis, Utkarsh Ambudkar, Chris Sullivan, Bill Sherman, James Monroe Iglehart and Andrew Bancroft.
