Sachs and Fugard
Sachs has the honor of being chosen by playwright Athol Fugard as one of the few directors in the United States to premiere his new plays. The collaboration between Fugard and Sachs goes back nearly a decade when Sachs directed the Los Angeles premiere of Fugard’s The Road to Mecca in 2000.
In 2004, Mr. Sachs had the privilege of being the first person, apart from the playwright, selected to direct the world premiere of a new play by Athol Fugard. Sachs directed the world premiere of Fugard’s Exits and Entrances in Los Angeles (3 LA Ovation Awards including Best World Premiere of a New Play and Best Director, 5 LA Drama Critics Circle Awards including Best Production and Best Director). He directed acclaimed regional productions of the play around the country. And he directed the Off-Broadway production at Primary Stages in New York in 2007(New York Outer Critics’ Circle Award nomination for Outstanding New Off-Broadway Play, selected as "Ten Best" Productions of 2006/2007 by New York Theatre Writers). He also directed the UK premiere at the 2007 International Edinburgh Festival in Scotland.
In 2008, Fugard gave Sachs the exclusive United States rights to his play, Victory. Sachs directed the United States premiere in Los Angeles and the production was named “Critic’s Choice” and “Best of 2008” in the Los Angeles Times.
Fugard chose Sachs to direct the West Coast premiere of his new play, Coming Home (“Critic’s Choice” Los Angeles Times) in 2009. The production has been nominated for a 2009 Ovation Award for "Best Production of a Play". Fugard has given Sachs his newest play, The Train Driver, which Sachs will direct as the U.S. premiere in the coming 2010 season.
ASL Theatre & Film
Sachs was instrumental in launching and supporting the Deaf West Theatre Company at the Fountain Theatre in 1991. The company won the Tony Award for its acclaimed ASL-version of Big River on Broadway in 2003. His play about deafness and cochlear implants, Sweet Nothing in My Ear, was recently made into a television movie starring Jeff Daniels and Marlee Matlin, and presented on the Hallmark Hall of Fame on April 20, 2008. The teleplay and adaptation are by Mr. Sachs himself, and the film was directed by Joseph Sargent.
