I wanted to wait for a bit but now with the casting for the upcoming Titans series pretty much complete, here's a round up of who else to expect on the show.
Alan Ritchson has been confirmed for the role of Hank Hall/Hawk in a recurring role for the series. This isn't the first time the Blood Drive actor has taken on a heroic role in the DC universe as he previously played Arthur Curry/Aquaman in Smallville in a recurring capacity as well. Hank is being described as offensive, aggressive bruiser who fights crime with his partner and girlfriend. Speaking of whom.
The role of Dawn Grainger/Dove will be played by Charlie's Angels actress Minka Kelly. The actress will appear in a recurring capacity along with Ritchson and has been described as a strategic, defensive and lithe vigilante who fights crime with her partner and boyfriend Hawk.
Elsewhere the role of Garfield 'Gar' Logan/Beast Boy - one of the four regular roles for the series has now been confirmed as Ryan Potter (Big Hero 6). Previously there was an online campaign by certain DC fans for the actor to play the role of Tim Drake/Robin in the DCEU but it seems that the actor will be taking on another heroic role.
Meanwhile Lindsey Gort (The Carrie Diaries) has been cast in the role of Amy Rohrbach, who has been described as a police detective who is the new partner of Dick Grayson (Brenton Thwaites). Presumably Amy will be the only character not to don a costume for the upcoming series.
