HBO is developing the limited series “The Chain,” with Jodie Comer set to star in the lead role. The project comes from Damon Lindelof, who is credited as showrunner/creator under his overall deal with HBO, and it is based on the novel “The Chain” by Adrian McKinty. Multiple outlets report that HBO has ordered the series as an eight-episode limited run. The story follows Rachel, played by Comer, a suburban mother who confronts a dangerous situation that forces her to make difficult choices. While details of the plot beyond the central premise are not fully outlined in the provided materials, sources characterize the series as a thriller. The Hollywood Reporter, Variety, and Deadline each identify the same core creative team—Lindelof as the driving force behind the adaptation and Media Res as associated production for the series—and agree on Comer’s casting as the lead for the upcoming HBO release.
