Luke Evans – Sinestro
As Green Lantern fans will tell you, Sinestro is the most iconic enemy of the Emerald Knights. Though once a Lantern himself, he was kicked out of the Corps due to his thirst for power, which led him to seek out the yellow power of fear. He’s a natural for the upcoming Green Lantern Corps, then, or as part of Luthor’s Legion of Doom.
Of course, the purple-faced antagonist previously appeared on screen in 2011’s Green Lantern, as played by Mark Strong. Admittedly, his casting was actually one of the few good things about the aforementioned Ryan Reynolds-starring flop, so our first choice would have been for the actor to have reprised his role.
However, Strong is already set to play another villain in the DCEU: Shazam!‘s Dr. Sivana. With him out of the running then, our next choice is Luke Evans. He’s shown his range in a few projects recently and it’s easy to imagine him looking the part with a bit of facial hair and make-up. Case in point: the above piece of art from BossLogic.
Dane DeHaan – Riddler
Despite being one of the Dark Knight’s most famous foes, we haven’t had a cinematic version of the Riddler since 1995’s Batman Forever, where he was campily played by Jim Carrey.
While Carrey’s performance worked for that movie, a modern interpretation could bring out the darker side of Edward Nygma: an unhinged genius compelled to play a battle of the wits with the Caped Crusader. An easter egg has already confirmed his existence in the DCEU, too, so let’s hope he shows up in some form in The Batman.
There are a number of actors we could imagine doing a good job of filling Eddie’s green question-marked suit, but our top pick is Dane DeHaan. Sure, the last time he played a supervillain things didn’t go too well – see his laughably poor Green Goblin in The Amazing Spider-Man 2 – but if you look back to his turn in Chronicle you can see how well he could portray the Riddler as a disturbing, dangerous individual.
