I'm not that experienced of a writer so I'll just get to the point. I would like to share my opinions on who I think should play the Bat-Family Robins, in the "DC Extended Universe".
1. Nightwing (Robin Dick Grayson)
First up is the original Robin Dick Grayson, who outgrew his persona and went on to become his own (and my number 1 favorite) hero - NIGHTWING
First Choice: Kit Harrington
Kit Harrington above is my first choice for Nightwing. To me he looks the part being the pretty boy, and has played (in my opinion) a similar character in Jon Snow. Jon Snow is a natural born leader with his own charisma that gets others around him to follow or believe in him. I have not seen Kit really play a light hearted character before, but I think he could pull off Dick Grayson very well.
Second Choice: Richard Madden
Now I know yes I am a Game of Thrones fan. But I personally believe Richard Madden also has what it takes to play Dick Grayson's Nightwing. He has the look, I've seen him in other roles besides Robb Stark, and from what I've seen I think he'd be a great choice.
Third Choice: Scott Eastwood
There has been a lot of rumors as to who Scott Eastwood is playing in the upcoming "Bad vs Evil" film Suicide Sqaud. We do know it looks to be a soldier who seems to work for Amanda Waller. But one of those rumors is that he could be Dick Grayson. In the comics in recent years, Batman has Dick fake his death and infiltrate a secret organization called Spyral. So if the DCEU runners wanted they could just swap out Spyral and put Argus, which is run by Amanda Waller who runs the Suicide Squad.
2. Red Hood (Robin Jason Todd)
Next is the second Robin Jason Todd, who was killed by the Joker not only in the comics, but now confirmed in Batman V Superman via the new Comic Con trailer. In one of the best Batman stories in comics and an awesome animated movie he is resurrected as anti hero RED HOOD.
First Choice: Jake Abel
I have seen Jake Abel in Percy Jackson & the Olympians: The Lightning Thief including its sequel, Supernatural, and I Am Number Four. In two out of three of those roles I have seen him play a forgotten son, who's bitter over the way his father treats him or his decisions. His performances imo remind me of Jason Todd and his aggressive nature, including his Bat daddy problems.
Second Choice: Drew Roy
Drew Roy from what I've seen has not only the look, but the acting chops needed to play Jason Todd/Red Hood. Nothing more to say than I think he'd be a good choice.
3. Red Robin (Robin Tim Drake)
Third on the list, is the third Robin Tim Drake. He's the best detective of all the Robins and arguably the best Robin. Batman himself once said "Dick saw being Robin as a thrill. It's probably why he outgrew it. Jason saw being Robin as a game. It's probably what got him killed. But...Tim...I have to hand it to the boy...He wants to be the world's greatest detective. And from what I've seen so far...he will be someday." Tim does at one point leave the Robin mantle behind to become RED ROBIN.
First Choice: Logan Lerman
Logan Lerman is someone I've seen on a lot of peoples fan cast for Tim Drake. But it's for good reason, I honestly believe he'd be perfect as Tim Drake/Red Robin. Watch any role he's played and if you know anything about Tim, you can see why he's fit for the role.
Second Choice: Josh Hutcherson
Josh Hutcherson is another actor who I think would be perfect for playing Tim Drake. He's been acting since he was child and has once again in my opinion, the acting ability to pull off a Tim Drake. It would honestly be tough to pick between Logan and Josh to me.
4. Damian Wayne
And Last on the list is the current Robin and actual blood son of Batman DAMIAN WAYNE. The likeliness of us ever seeing him in the DCEU is very slim even more so than the other Robins on the list but what the heck.
First Choice: Chandler Riggs
I believe he is an amazing child actor, and you need to be exactly that to play as Damian Wayne son of Batman. Damian is a bad ass kid who is very intelligent for his age, obviously it's in his blood. And I believe Chandler can play Damian probably to perfection.
Second Choice: David Mazouz
And yes I know he is already playing Bruce Wayne on Gotham, but I believe he's doing very well already in his one season as the future Batman. I think David can play Damian who is similar to Bruce in his young days. I would hope being in Gotham wouldn't be a negative in his chances, if there ever was one.
Who would you pick as Nightwing from my choices?
Who would you pick as Red Hood Jason Todd?
Who would you pick as Red Robin, Tim Drake?
Who would you pick as Damian Wayne's Robin?
