NBC is getting a little slap-happy.

The network has added Thandie Newton and Melissa George to its upcoming miniseries, The Slap, which is based on the 2011 Australian project of the same name. Written by Jon Robin Baitz (The West Wing), The Slap is described as “a complex family drama that explodes from one small incident where a man slaps another couple’s misbehaving child.” From there, secrets are exposed, a lawsuit is filed, and all kinds of drama ensues in the miniseries, which has an eight-episode order.

Newton and George join a cast already featuring Peter Sarsgaard, Mary-Louise Parker, Zachary Quinto, and Brian Cox. Thandie will play Aisha, wife to Hector (Sarsgaard), mother to two kids, and a doctor. Aisha is described as a very organized person who arranges her husband’s birthday party only to get irritated at the arrival of her in-laws. As she tells her husband, “We’re just very busy and tired people with two kids and a houseful of agitated guests.”

As for George, who also appeared on the Australian version of The Slap, she will play Rosie, “Gary’s hippy wife and mother to 5-year-old Hugo on whom she lavishes smothering affection. Defensive about her decision to keep Hugo at home rather than send him to preschool, she is a meddlesome mom, scolding the older children whom she thinks are bullying her precious son.” And you can only imagine what happens when she learns that Hugo was slapped by Harry (Quinto).

No air date has been set for the miniseries.
