What’s on TV

BREXIT (2019) 9 p.m. on HBO; stream on HBO Go or HBO Now. After an earlier introduction in Britain, the feature-length drama “Brexit” hops across the pond to tell the story — or one possible version — of how the British referendum on leaving the European Union resulted in the narrow triumph of the Leave campaign. Written by the political playwright James Graham, the movie follows the Vote Leave campaign manager, Dominic Cummings (Benedict Cumberbatch) as he ignites a dormant group of voters to “take back control” with strategies to overwhelm the Remain campaign and its leader, Craig Oliver (Rory Kinnear). As the Brexit controversy continues to send shock waves around the world, the only film yet to attempt to unravel the chaos may do the same.

ESCAPING THE MADHOUSE: THE NELLIE BLY STORY (2019) 8 p.m. on Lifetime. Nellie Bly, the famed female journalist, is the stuff of legend — and so is this drama detailing her infiltration of the Women’s Lunatic Asylum (based on the real New York City institution on Blackwell’s Island). Inspired by Bly’s real-life investigation into the mistreatment of mentally ill patients, this movie, starring Christina Ricci, brings a dark intensity to the deplorable conditions Bly experienced, with several cinematic twists.
