TNT has given the greenlight to three new original series, the network announced Thursday. The three pick-ups are an untitled alien-invasion show from executive producer Steven Spielberg, in which Noah Wyle stars as the leader of a group of soldiers and civilians struggling against an occupying alien force; Delta Blues, produced by George Clooney and starring Jason Lee as a Memphis police officer who lives with his mother; and Rizzoli & Isles, a crime drama starring Angie Harmon and Sasha Alexander. TNT has ordered 10 episodes of each show, with plans to have Delta Blues and Rizzoli & Isles premiere this year. Spielberg’s alien-invasion series is scheduled to debut in 2011.
