Former Doctor Who star David Tennant has joined Marvel’s Netflix series A.K.A. Jessica Jones as the villain Zebediah Killgrave, who himself as an A.K.A.: The Purple Man! Krysten Ritter stars as the title character while Mike Colter will play Luke Cage on the show before getting his own series as well. Killgrave plays a major role in Jessica Jones’ life in the comics, but it remains to be seen how much the show will match his and Jessica’s story from the printed page.
