The cast for J.J. Abrams' latest TV venture keeps filling out. According to The Hollywood Reporter, actor-writer Ben Schwartz has come aboard Undercovers as an actor.

Schwartz will join the cast that already includes Boris Kodjoe and the very recent addition Gugu Mbatha-Raw, who will play Steve and Samantha, a husband-and-wife pair of ex-CIA agents who go back into the field together. Schwartz will play a fellow CIA operative, who worships Steve's career as an agent.

J.J. Abrams will direct the pilot, which he co-wrote with Josh Reims. Schwartz is also a performer and writer at Upright Citizen's Brigade, who brought home an Emmy as part of the team that wrote Hugh Jackman's opening monologue at last year's Oscar ceremony.
