Thomas Sadoski (The Newsroom) has been cast in NBC’s eight-episode miniseries The Slap. Based on the 2011 Australian short-run series, The Slap is described as a complex family drama that explodes from one small incident where a man slaps another couple’s misbehaving child. Sadoski, repped by UTA and Industry Entertainment, will play Gary, something of a hippie, husband to Rosie (Melissa George) and father to Hugo. Cajoled by his wife into attending Hector’s birthday party, Gary quickly gets irritated when talk turns to getting into the right preschool and “getting ahead.” Fueled by too many beers, he gets into a heated discussion with Harry, ready to press charges when Harry slaps his son. Sadoski next will appear in features Wild and Take Care, both set for a December 5 release.

Michael Nathanson (Side Effects, The Wolf Of Wall Street) has been upped to series regular in the second season of Cinemax’s period drama The Knick. Steven Soderbergh directs and Clive Owen stars in the series set in downtown New York in 1900. It centers on Knickerbocker Hospital and the groundbreaking surgeons, nurses and staff who push the bounds of medicine in a time of astonishingly high mortality rates and zero antibiotics. Nathanson, repped by Innovative Artists and Lillian LaSalle at Sweet 180, will reprise his role as Dr. Levi Zinberg — a brilliant surgeon and inventor who is the nemesis to Dr John W. Thackery (Owen) — which he played in Episodes 8 and 10 of Season 1. Nathanson is next set to co-star in Eric Daniel Metzgar’s feature The Assembly Of Gasping Fish.
