Zachary Quinto and Brian Cox Board The Slap

ON

Brian Cox (Manhunter, “Nuremberg”) and Zachary Quinto (“Heroes,” Star Trek) have both joined the cast of the upcoming NBC miniseries, “The Slap,” reports Deadline. They join the previously-announced Mary Louise Parker and Peter Sargaard.

Based on the 2011 Australian project of the same name, “The Slap” is written by Jon Robin Baitz (“The West Wing,” “Brothers & Sisters”) and produced by Universal Television. It offers a complex family drama that explodes from one small incident where a man slaps another couple’s misbehaving child. This seemingly minor domestic dispute pulls the family apart, begins to expose long-held secrets, and ignites a lawsuit that challenges the core American values of all who are pulled into it.

Baitz, who was a Pulitzer finalist for his semi-autobiographical play “A Fair Country,” will write all episodes and executive produce with Walter Parkes, Laurie MacDonald, Ted Gold and Tony Ayres.
