I got it wrong. It seems like Brenton Thwaites is going to be portraying the Boy Wonder rather than the grown up counterpart in the first season of DC's streaming service series, Titans.
The series, due to air online in 2018 released a photo of Brenton as Dick Grayson/Robin last night and it seems going by the reaction, that people are rather pleased with this look. While it would've been nice to have had a body shot one (as well as pictures of Raven, Starfire and Beast Boy), it does seem like they've got the look of the Boy Wonder rather on point. It also makes me wonder if we're going to see over the course of the first season Grayson transition from Robin to Nightwing, with the latter factoring into a likely second season.
The series pilot is written by Geoff Johns (current DC movie universe), Greg Berlanti (the current Arrow universe) and Akiva Goldsman, who also penned Batman Forever and Batman & Robin. The director or episode count for the series has yet to be confirmed but given this reveal, I'm guessing a lot more information will be soon coming regarding the upcoming series.
