One’s a bestselling Oprah’s Book Club pick, the other’s a Kirkus-starred tale of romantic angst—and both received new premiere dates for their upcoming prestige-TV miniseries.

HBO had originally scheduled the first episode of I Know This Much Is True, its series based on the 1998 Wally Lamb bestseller, to air on April 27. On Tuesday, the network announced that the six-episode, Mark Ruffalo-starring production had been delayed to May 10.

I Know This Much Is True, which tells the story of troubled identical twins, is taking the place of another, previously scheduled HBO crime-drama miniseries, The Undoing, whose production has been delayed due to the COVID-19 pandemic, according to Variety. That series, which stars Nicole Kidman and Hugh Grant, is based on Jean Hanff Korelitz’s 2014 novel You Should Have Known; its first episode has been postponed to an unspecified date in the fall.

Hulu also released a trailer on Tuesday for its upcoming 12-part miniseries of Sally Rooney’s Kirkus-starred 2018 novel, Normal People, about a young Irish couple’s fraught relationship. The Hulu/BBC Three co-production, starring Daisy Edgar-Jones and Paul Mescal, will premiere on the streaming service on April 29.
