Zoo star James Wolk is set for a guest arc opposite Billy Bob Thornton in the second season of Amazon’s praised drama series Goliath. The new season is executive produced by Peabody Award winner Clyde Phillips (Dexter), who serves as showrunner. The series is created by David E. Kelley and Jonathan Shapiro.

Wolk will play FBI Special Agent Jeff Clayton, who agrees to help Billy (Thornton) hunt down his prime suspect in the Marcos Pena murder, who was last seen in ICE custody. Meanwhile, Jeff shows a romantic interest in Patty (Nina Arianda).

Wolk stars as Jackson Oz on CBS’ Zoo and recently recurred on Billions. He’s repped by ICM, Greenlight Management and Frankfurt Kernit.
