Josh McGuire will go Underground

Manager joins Trevor Engleson and Nick Osborne firm

NEW YORK -- Josh McGuire, a young manager who counts Black List scribe Jason Micalleff among his clients, has joined Trevor Engleson and Nick Osborne's Underground Management.

McGuire comes from Washington Square Arts, where he repped a host of lit clients, including Micalleff, the writer behind "Butter." That script was the third-ranked screenplay on last year's Black List and is set up at Mandate with Jennifer Garner attached to star.

McGuire had been at the boutique Washington Square Arts for three years. Underground reps up-and-comers such as "War of Gods" scribes the Parlapanides brothers as well as the Hageman brothers, who are writing Warner Bros.' new Lego project.

The company also counts "License to Wed" and upcoming Robert Pattinson drama "Remember Me" among its producing credits.
