There's been little word regarding the upcoming Teen Titans based television series on TNT since it was announced a few months back. The only aspect we knew for sure was that Nightwing would be the leader.
Now according to The Nerdist, who received casting information for the pilot, this is the line-up that will grace the first episode:
Hawk and Dove
While all of these characters have appeared in animated form in some aspect or another, only Oracle has shown up in live action before (in WB's short-lived Birds of Prey), though of course Dick Grayson has been represented multiple times as Robin in various media.
According to the report, Hawk and Dove will be based on their New 52 iterations and are a romantic pairing. Also, the pilot script never actually refers to Barbara as Oracle, though she serves as the "computer hacker" of the team.
The lack of Beast Boy/Changeling and Cyborg may surprise some, though with the upcoming film already scheduled for the latter and his participation in Zack Snyder's Justice League, Vic Stone has surely graduated to the big squad on a permanent basis.
It's very likely that TNT's Titans will air sometime before the end of 2015.
