Warner Bros. TV is rapidly expanding its live-action DC Comics TV universe. This season, it is going from one to four primetime series, returning Arrow and freshmen The Flash, Gotham and Constantine, and already is prepping another major broadcast franchise with Supergirl. Now the studio is expanding the DC brand to cable drama with Titans, a project that is nearing a pilot order at TNT. Titans is one of three TNT drama pilots stuck on the runaway, awaiting a formal green light as the network is undergoing a regime change. The other two are Lumen from Amblin TV and the Jerry Bruckheimer and Michael Bay-produced Cocaine Cowboys.
