Although Dick Grayson is currently being depicted in live action on the DC Universe series Titans, and Michael Cera voiced the character in The LEGO Batman Movie, it’s been since 1995’s Batman Forever and 1997’s Batman and Robin since we last saw Robin depicted in a live action movie, where he was played by Chris O’Donnell (no, I’m not counting ‘Robin’ John Blake from The Dark Knight Rises).
Batman v Superman: Dawn of Justice did show a graffitied Robin suit on display in the Batcave, but that was a reference to the Jason Todd incarnation.
