Zack Snyder’s Justice League cast has grown once more, adding Ciaran Hinds - best known for playing Mance Rayder in Game of Thrones - to its already stellar line-up.

According to The Wrap, the prolific Irish actor will play the CGI villain Steppenwolf, a character hinted at in a deleted scene from this year’s Batman v Superman in which Jesse Eisenberg’s Lex Luthor communicates with an intergalactic being through the downed Kryptonian ship.

Also seen in the scene are three mysterious floating boxes which fans of the comics will instantly recognise as Mother Boxes, all three of which are located on earth.

The aforementioned publication confirms the villain will hunt down all three in the film: one is located in Atlantis (Aquaman’s home), one in Themyscira (Wonder Woman’s home), and one is now a part of Justice League member Cyborg.

Yes, it is another Spider-Man reboot, having previously been redone with Andrew Garfield as the lead. However, this time it is part of the MCU, with Tom Holland as the titular character, and a heavily rumoured cameo by Iron Man could be in the pipeline. We can dream. 33 Superhero films set for release between 2016 and 2020 10. Untitled Fox film Release date: 6 October 2017. In a strange announcement, Fox decided to withhold the release of Gambit until a future, as-yet unannounced date, which could be here, or this could be a completely separate project. Many suspect Deadpool 2 could nicely fit here, Fox capitalising on the success of the first film. 33 Superhero films set for release between 2016 and 2020 11. Thor: Ragnarok Release date: 3 November 2017. Chris Hemsworth will be returning as the Norse God in his third solo MCU film. Flight of the Conchords’ Taika Waititi is on board to direct, and promises a fun adventure that will likely lead into Marvel’s next project, Infinity War. 33 Superhero films set for release between 2016 and 2020 12. Justice League Part One Release date: 17 November 2017. Hot on the heals of Thor comes Justice League Part One, the first DCEU team-up flick which will see Batman, Superman, Wonder Woman, The Flash, Aquaman and Cyborg work together to fight bad guys. 33 Superhero films set for release between 2016 and 2020 13: Untitled Fox film Release date: 12 January 2018. Kicking off 2018 will likely be the second Deadpool film, but then again, this could very well be another X-Men team-up. There’s also talk of an X-Force film, with Deadpool and other mutants teaming up to fight evil. 33 Superhero films set for release between 2016 and 2020 14. Black Panther Release date: 16 February 2018. The first non-white male-led superhero film in the MCU comes in the form of Black Panther, with Chadwick Boseman reprising the titular role, having also starred as the Panther in Civil War. Creed’s Ryan Coogler is on to direct what could be a very exciting film. 33 Superhero films set for release between 2016 and 2020 15. The Flash Release date: 16 March 2018. The Flash will be the first DCEU film since Justice League, and sees Ezra Miller take the lead.

Avengers: Infinity War Part 1 Release date: 4 May 2018. And so, we finally get to the point of all these Infinity Stones! Thanos will be the big bad, with the Avengers needing to team up to defeat their biggest foe yet. It has previously been described as “the end of the Avengers as we know it”. 33 Superhero films set for release between 2016 and 2020 17. Ant-Man and The Wasp Release date: 6 July 2018. Peyton Reed will be back to direct this surprise sequel to one of the better received MCU films. While the name is ridiculous, at least Marvel are finally having a leading female superhero. 33 Superhero films set for release between 2016 and 2020 18. Untitled Fox film Release date: 13 July 2018. Again, not much word on this one except it is thought to be X-Men spin-off New Mutants, something Josh Boone has been hit up to write. 33 Superhero films set for release between 2016 and 2020 19. Animated Spider-Man Film Release date: 20 July 2018. Avi Arad, Matt Tolmach, and Amy Pascal - the team behind the live-action Spider-Man films - are producing this ‘unrelated’ animated adaptation of the hero. Because you can never have too much Spider-Man, right? 33 Superhero films set for release between 2016 and 2020 20. Aquaman Release date: 27 July 2018. Another Justice League spin-off, Jason Momoa plays the leading man. Furious 7’s James Wan is on to direct, but little else is known about the film. 33 Superhero films set for release between 2016 and 2020 21. Captain Marvel Release date: 8 March 2019. We’ve hit 2019, and the first confirmed superhero film will be the first proper female-led MCU film.

Dwayne Johnson stars as the villain in this DCEU film which will be somewhat separate to the other DC films. 33 Superhero films set for release between 2016 and 2020 23. Avengers: Infinity War Part 2. Release date: 3 May 2019. The conclusion to the long drawn MCU saga. Expect a big finish with at least a few planets being destroyed. 33 Superhero films set for release between 2016 and 2020 24. Justice League Part Two Release date: 14 June 2019. Soon after the Infinity War story reaches its conclusion, so will the Justice League’s. Not much is known, except Darkseid will likely be the villain for at least one of the parts. 33 Superhero films set for release between 2016 and 2020 25. Inhumans Release date: 12 July 2019. The concept of Inhumans (or Marvel’s mutants) has already been introduced in TV, through Marvel’s Agents of Shield, yet the film is expected to introduce the Royal Family who have yet to be seen in the show. 33 Superhero films set for release between 2016 and 2020 26. Cyborg Release date: 3 April 2020. Having debuted in Justice League Part One three years previously, Cyborg will finally be making his own outing, with Ray Fisher as the titular character. 33 Superhero films set for release between 2016 and 2020 27. Untitled MCU film Release date: 1 May 2020. The first of three untitled Marvel films. There are a couple of contenders, the first is a likely sequel to Spider-Man with Sony, or a third Guardians of the Galaxy film, thus finishing the trilogy. 33 Superhero films set for release between 2016 and 2020 28. Green Lantern Corps. Release date: 19 June 2020. Before you start to worry, this has nothing to do with the Ryan Reynolds-starring flick that hit cinemas a little while ago. Instead, this will be another DCEU film that will likely spin-off from Justice League after the Green Lantern Corps cameo in one of the parts. 33 Superhero films set for release between 2016 and 2020 29. Untitled MCU film Release date: 10 July 2020. As well as Spider-Man or Guardians of the Galaxy sequels, a Doctor Strange or Black Panther one could fit in nicely here. Or perhaps Black Widow may finally get the solo-film she deserves. 33 Superhero films set for release between 2016 and 2020 30. Untitled MCU film Release date: 6 November 2020. Some speculators also think a Blade film could fit in here, marking over 20 years since the first Blade. But many believe the character may be better suited to a Netflix series, as with Daredevil and Jessica Jones. There’s also talk of a Runaways film reaching cinemas at some stage. 33 Superhero films set for release between 2016 and 2020 31. Untitled Ben Affleck Batman film Release date: TBA. Now we’re onto the TBA release dates, the first of which is a Batman solo film, written and directed by Ben Affleck. When this is due, no one is quite sure but expect it sooner rather than later if Batman v Superman is a success. 33 Superhero films set for release between 2016 and 2020 32. Suicide Squad 2 Release date: TBA (rumoured 2017). A sequel to Suicide Squad is expected to come in 2017 according to recent reports, but nothing has been confirmed. If the first is successful, it should come as no surprise for Warner Bros to rearrange their schedule to fit in this surefire hit. 33 Superhero films set for release between 2016 and 2020 33. Venom Release date: TBA. This is an odd one, as it has been confirmed Sony are wanting to release a Venom film completely unrelated to the upcoming Spider-Man reboot. Venom, as you may know, is a Spider-Man villain, intrinsically linked to Spider-Man, so it seems odd they would release a film unrelated to the rebooted project and not linked to the MCU. 33 Superhero films set for release between 2016 and 2020 Anything else? Well, now you mention it, there’s also that sequel to Fantastic Four that has seemingly been dropped by Fox. Plus, there’s the Gambit film which has been put on hold (but will likely fill an untitled Fox slot so we haven’t added it extra). Then again, it could be shoehorned in somehow… Marvel

“[Back] before there was a history … mankind, the Atlanteans — before they were under water — the Amazonians and, actually, the old gods, teamed together and decided that — based on an event that happened — these mother boxes were going to be placed in the care of, as I say, the Amazonians, mankind and the Atlanteans,” producer Charles Roven said. “So that allows us to get into some of those environments.”

While featuring these locations for the first time, the packed film will also serve to introduce Jason Momoa’s Aquaman, Ray Fisher’s Cyborg, Ezra Miller’s The Flash (to a certain extent), J. K. Simmons’s James Gordon, Willem Dafoe’s Nuidis Vulko, Amber Heard’s Mera and Julian Lewis Jones’s unnamed character.

If that wasn’t enough for you the film also sees the return of Ben Affleck’s Batman, Gal Gadot’s Wonder Woman, Amy Adams’s Lois Lane, Jeremy Irons’s Alfred, and Jesse Eisenberg’s Lex Luthor. Oh, and Snyder needs to resurrect Henry Cavil’s Superman. Phew.
