Bruce will play Bartholomew “Bart” Winslow, the trophy husband of Corrine (played by Scrubs‘ Heather Graham), a recent widow who puts her four children into a pretty terrible situation at her parents’ mansion after their father’s death. A disturbing family secret causes the children’s grandmother, Olivia (Political Animals’ Ellen Burstyn), to lock the children in the attic, where the oldest boy (Mason Dye) and girl (Mad Men‘s Kiernan Shipka) develop an inappropriate bond.

Bruce — who co-stars as military man Paul on the BBC America thriller Orphan Black — recently booked a two-episode guest spot on The CW’s Arrow.
