Watch Colman Domingo in the Sing Sing trailer

Sing Sing is by director Greg Kwedar and stars Colman Domingo, Clarence Maclin, Sean San José, and Paul Raci.

A theater group escapes the reality of incarceration through the creativity of staging a play, with a cast that includes actors who have been incarcerated.

This looks like it will be a powerful movie.

Kwedar (“Jockey”) co-wrote the film with Clint Bentley.

The film will have its U.S. premiere at the SXSW Film Festival on Friday and is set for theatrical release in July.
