The Hollywood Reporter

The sci-fi action series based on Bong Joon Ho's 2013 film of the same name, starring Jennifer Connelly and Daveed Diggs, was first put into development in November 2015. The May 31 premiere will come almost exactly three years after Diggs and Connelly signed on for the series, which had been plagued with problems. At the TV press tour, showrunner Graeme Manson explained: "It takes a long time to get it right. We got it right."
