EXCLUSIVE: Topher Grace’s musical comedy One Shot has added another crooner to its cast. Singer-songwriter and record producer JC Chasez, a founding member of the seminal boy band *NSYNC, will join Grace and Taye Diggs in the film about a failed Broadway performer turned stage manager who must wrangle the eccentric cast and crew of a new play to save the show’s opening night.

Grace is starring as said stage manager in addition to producing the indie film, which shoots next month in Mexico City. Chasez will play Grace’s nemesis, the star of the musical play within the movie who sleeps with his ex-girlfriend. Isaac Rentz is directing from a script by Gerry De Leon and Greg Lisi. Daniel Posada and Jason Tamasco are also producing One Shot for Mexico-based Dark Factory Entertainment with Alex Garcia of AG Studio.

Chasez dabbled in acting with guest starring roles on TV and indie films after dominating the pop charts alongside fellow lead *NSYNCer Justin Timberlake, who himself went on to build a serious acting career. Chasez also spent seven seasons as a judge on MTV and Randy Jackson’s America’s Best Dance Crew reality TV competition and recently appeared in action thriller Red Sky. And what fan of the ’90s-era Mickey Mouse Club could forget his early acting turns on that Disney talent showcase and its spinoff serial, Emerald Cove?

Chasez is repped by Pantheon and Podwall Entertainment.
