Finally, after such a long wait, Warner Bros. has decided to make Justice League Dark a priority. For years, Guillermo del Toro has teased this project, even handing the studio a final version of the script. Unfortunately, the director then decided to leave the movie, even if he wanted to direct it as well, since the studio didn't have any idea what to do with it.

But then again, maybe it was for the better - Doug Liman (Edge of Tomorrow), who was supposed to direct Gambit for Fox (but dropped out because of the delays), will helm Justice League Dark. And, while there isn't a scheduled release date (the rumors say that it will be sometime in 2018), we already know the roster - Constantine, Zatanna, Deadman, Swamp Thing, and Etrigan the Demon.

Of course, it will be interesting to see who will be cast in the movie. However, the most interesting is Constantine, who has already appeared on both film and TV series. On film Keanu Reeves did, well, an interesting job, while Matt Ryan's show was cancelled after just one season.

So who could bring Constantine to life on the big screen once again? Here are the top choices!

Luke Evans

I know - Luke Evans is rumored to have been approached to portray Sinestro in the Green Lantern Corps movie. However, that is just a rumor. And, quite frankly, he'd be a better fit for Constantine, in Justice League Dark. Does he have the acting chops to bring the character to life?

Not exactly. However, he did have some pretty interesting roles, and his dramatic takes on various characters are actually satisfying. Thus, while he isn't a superstar, he did have roles in high-profile movies, such as The Hobbit Trilogy and Fast and Furious.

Plus, he does have the charisma needed for such a role. I guess Justice League Dark won't make the most of his physical abilities. However, the role would certainly benefit from his coolness.

Justice League Dark will be an ensemble movie. And Luke Evans shines in these kinds of flicks. So I say that he is a competent choice for Warner Bros. to make.

Daniel Craig

Reportedly, Daniel Craig was offered $150 million to make the next 2 Bond installments. So we can say for certain that he is an expensive actor. However, if we look at the box office take of his Bond flicks, he surely deserves his paychecks.

This being said, I don't think that Daniel Craig will want to make more Bond flicks. Sure, his statements concerning the future of this franchise can be considered a bargaining strategy. So what if he jumps in the DCEU boat instead?

One of the roles which would recommend him as Constantine isn't the Bond one. Instead, take a look at Layer Cake. It was quite an awesome role, wasn't it? Justice League Dark will bring him back the possibility of portraying a similar role.

And I guess that he is tired of being Bond for the past 10 years. To be noted, Rachel Weisz appeared in the Keanu Reeves version of Constantine. So he could take some pointers from her (also, in this family, she is the Academy Award winner, so he could definitely have her teach him some tricks).

Ewan McGregor

Back when Guillermo del Toro revealed that he was working on a Justice League Dark script, the name of Ewan McGregor was the only one to be mentioned. It wasn't revealed, however, which role Warner Bros. wanted him for. But I guess it is safe to assume that it was Etrigan the Demon.

Ewan McGregor has the acting chops to portray such a dark character. I am not talking about the Star Wars prequels, for which he is best known.

Besides the skills, he actually looks the part. He's got the accent, the hair looks alright, what more does he need? Sure, this casting would ignite some of the fans on the web. But it isn't as if he is the first one to meet such a response.

Ewan McGregor will reprise the role which made him famous in the sequel for Trainspotting. I don't know about late sequels and how they will perform - but I would definitely watch him as John Constantine in Justice League Dark.

Ethan Hawke

Here is another interesting actor, maybe too much overlooked, who could do a great job in Justice League Dark. Ethan Hawke isn't known for taking roles in big blockbusters. However, this is what actually recommends him - the fact that he feels confident enough to take roles in smaller and much more demanding movies.

It would be a change for him, one that might actually catapult him to superstardom.

He isn't known for action flicks. But Justice League Dark won't be one. And Ethan Hawke has played in numerous dark movies until now - Sinister is by far the best example. And his acting chops can be seen all over the place, from Gattaca to Training Day to the Sunrise, Sunset, Midnight trilogy.

So, if Ewan McGregor ends up being Etrigan the Demon, maybe Warner Bros. should consider Ethan Hawke for Constantine. After all, he does have two Oscar nominations to his name (and two more, but as a screenwriter).

Michael C. Hall

If until now I've chosen only big screen stars, Michael C. Hall changes all that. Sure, his most well-known roles are in TV series, whether we are talking about Dexter or about Six Feet Under. But the performances he had in these TV shows do recommend him for a Dark Universe role.

Until now, there haven't been too many actors to make a successful transition from the small to the big screen. But Michael C. Hall does have a chance. He is no George Clooney, but he does have the charisma and the acting chops.

Furthermore, this actor has the experience one would need in order to portray a character suffering from cancer. He also had it, so he can draw from his past experiences in order to bring the troubled Constantine to life.

As said, he isn't as big a name as others on this list. However, I am more than certain that he can own this character and bring a unique perspective to it.

Guy Pearce

Guy Pearce, for the comic book movie fans, is best known for his take on Aldrich Killian in the very divisive Iron Man 3. However, he had much bigger and more important roles before that. Memento is, obviously, the first one to come to mind. And then there is also LA Confidential, where he shines among actors such as Kevin Spacey and Russell Crowe.

Of course, the biggest question is whether he'd want to appear in another comic book movie, one that is bound to be filled with CGI. But, if he does, he can certainly deliver an incredible performance.

He has the right suaveness for the role - he is charming, but there is also something unlikeable about his persona. And this is a great mix, especially when it comes to portraying a hardened character who has seen it all.

Guy Pearce is, in my opinion, another interesting choice for Constantine in Justice League Dark. Although I doubt that Warner Bros. would take him into account (he does have a pretty busy schedule), I wouldn't be too surprised if he was announced.

Joel Edgerton

Joel Edgerton is the kind of actor who doesn't receive the attention he deserves. Sure, he was at one time on Marvel's list, being eyed to portray Star Lord. However, it didn't work out. And maybe it’s for the better, especially since he is an actor that doesn't really (want to) steal the show.

But this is great - since Justice League Dark is an ensemble movie and Constantine isn't the jester Star Lord is, Joel Edgerton is perfect for the role. There is an aura of mystery surrounding him (not literally, of course), which would fall perfectly in line with this character.

And he does have awesome acting skills, which can be revealed in both action and dramatic roles. Warrior, Black Mass, and Midnight Special are the best examples in this case. Sure, he did have some misfires (Exodus: Gods and Kings), but who hasn't?

Joel Edgerton hasn't appeared just yet in a comic book movie. Maybe this is the right time for his star to shine. I am more than certain that he would make a great Constantine, just like the others on this list.

Simon Pegg

There is literally nothing that recommends Simon Pegg as a viable actor for Constantine. He is a comedy actor, he seems to be a bit on the chubby side, and he is, basically, what Constantine isn't. However, as we all know, he’s a geek, he’s a nerd who actually takes pride in being one.

Sure, his Constantine wouldn't be pulled straight from the comics. However, neither was Keanu Reeves' - and it was still considered a success. So why not Simon Pegg? The actor could have a blast playing this role, and this is always an important thing.

Plus, Pegg isn't exactly a leading actor, his biggest and most successful movies being ensemble movies. Star Trek, Mission Impossible, and even the Cornetto Trilogy fall in this category.

So why not? I'm certain he can pull it off!

Very Special Mention

Paul Bettany is, right now, Vision in the MCU. For quite a while he was the voice of J.A.R.V.I.S. And while Thanos might be after Vision's infinity stone, I don't think the actor will part ways with the MCU anytime soon.

This being said, he is more perfect (if I may say so) for the role of John Constantine than any other actor on this list. Sure, he may not be the most talented, but he does look the part. Furthermore, he has actually appeared in quite a few movies with a supernatural angle.

Thus, while nothing could have saved Legion, his role in Priest (another dud) was awesome - if only he had a better script to work with, and if only the movie wasn't cut to hell before release.

So yeah - Paul Bettany is by far the best actor to bring John Constantine to life in a Justice League Dark movie. But that won't happen, no matter how many fans believe it.

Colin Farrell

Colin Farrell is the last on this list not because he isn't a skilled actor - but because the rumor is that Warner Bros. is already courting him for the role. And since Farrell has surrounded himself with the aura of a bad boy (who has aged quite well, actually), I don't see why this rumor wouldn't be true.

He'll next appear in Fantastic Beasts and Where to Find Them, which is another Warner Bros. movie. So why not? The studio does trust him.

Sure, he's had quite a few duds in his career - Total Recall is just one of them, while the second season of Tre Detective was atrocious. But he also gave us The Lobster, In Bruges, Seven Psychopaths, and even Fright Night (come on, that remake was actually awesome).

So Colin Farrell - what do you think?

Which one of these actors should bring John Constantine to life in Justice League Dark?
