Newest Additions to 'X-Men: Apocalypse': Alkali Lake Set Confirmed

May is the month of superhero movies this year, Captain America: Civil War (2016) premieres later this week, and X-Men: Apocalypse (2016) has a premiere date later this month on the 27th. As for Captain America: Civil War, spoilers and information on the film are being released at a constant rate. The same can be said of X-Men: Apocalypse with it's imminent release, but there's a far more substantial amount of mystery behind the X-Men: Apocalypse. We're privy to a known cast of mutants, but an entire legacy of mutants has been added to the original team introduced in X-Men: First Class. Some of which we have no idea who they are yet, and just may have pivotal futures in the 'X-Men' franchise.

Newest additions to the cast of X-Men: Apocalypse (2016) in undetermined roles.

In terms of audience knowledge, the general concepts of X-Men: Apocalypse are well known to be focused on the villainous, Apocalypse attempting to destroy the world, wherein the 'X-Men' are called upon to stop Apocalypse and his Four Horsemen. Promotional footage for the film has depicted a decent picture of the known mutants of X-Men: Apocalypse but there will be more mutants in the film than one can count. Though, information on the new mutants being introduced to the 'X-Men' franchise is scarce at the moment. There are quite a few actors set to have roles in X-Men: Apocalypse but are currently undetermined. These are some of the actresses and actors whom have been cast in X-Men: Apocalypse in undetermined roles. They may turn out to be pivotal characters within the film. According to the IMDB credits page for the Full Cast of X-Men: Apocalypse, these are the actors/actresses whom have been cast in unconfirmed roles in the film.

1. Ryan Hoffman

Ryan Hoffman has been listed as playing 'Mr. Summers' in the film. Meaning that he could be the father of Scott Summers (Tye Sheridan). There's also the matter of Alex Summers (Lucas Till) reprising his role in the film, which could see more members of the Summers family present during X-Men: Apocalypse . With the potential casting of Ryan Hoffman as 'Mr. Summers', it drives the question if Mr. Summers is indeed the father of Alex and Scott Summers. In that circumstance, it would mean that Ryan Hoffman is playing the galactic faring, Corsair.

Corsair has a history as an intergalactic traveler in Marvel Comics, he's also the legitimate father to Scott Summers/Cyclops and Alex Summers/Havok. Though it is possible that someone who says his name is 'Mr. Summers' in the film may not be so. There's the possibility of someone masquerading as Scott and Alex's father, Corsair or Mr. Summers. With that possibility rearing its ugly head, the role of 'Mr. Summers' played by actor, Ryan Hoffman could turn out to be a disguised Mister Sinister. To take a step back, Nate Grey has also been seen in the trailer for X-Men: Apocalypse which means that the character of Mister Sinister isn't far away from the action.

The implication Mister Sinister has on the 'X-Men' universe is that he's the mutant responsible for creating Nate Grey, with the use of genetic material gathered from Scott Summers and Jean Grey. It's possible that the reason Nate Grey exists in the current 'X-Men' cinematic universe is because Mister Sinister has been masquerading as 'Mr. Summers' for an undetermined period of time, in which he's been able to gain a full genetic sample of Scott Summers' blood, as well as a sample of Jean Grey's blood to successfully create the perfect mutant in 'Nate Grey'.

The role of Mister Sinister is been highly speculated to have been included in X-Men: Apocalypse and we may just get to see a portrayal of the character after all with Ryan Hoffman. A new screenshot from the trailer for X-Men: Apocalypse is embed above, possibly an image of Mister Sinister' on the right side of the temple, away from En Sabah Nur/Apocalypse. Ryan Hoffman is likely to be playing a disguised version of Mister Sinister, if that is his role within the film.

2. Christopher Tyson

Tyson is set to play someone of the Mutant group, the Morlocks. But his character information ends there. There's no current or past mutant of Marvel Comics known as Morlock, simply an entire group. In any scenario, the mutant Morlocks are likely going to be seen in X-Men: Apocalypse and Christopher Tyson is the only actor listed as a mutant Morlock which means that he's most likely the leader of the Morlocks. In most incarnations of the Morlocks in Marvel Comics, the leader of the mutant group was usually Marrow.

In the circumstance that Christopher Tyson is playing 'Marrow', it would be a parting way from the comic-book character of 'Marrow' as she's of the female gender. There's nothing that says a different incarnation of the character can't be seen on-screen, but with most of the mutants appearing X-Men: Apocalypse appearing loyal to their comic-book counterparts, it's likely that the leader of the Morlocks will be a different mutant, played by Christopher Tyson. My guess is that Tyson is playing the mutant, Masque. The character is of no real relevance but he has ties to the character of Caliban (Tomas LeMarquis) who has been confirmed in the film.

3. Fraser Aitcheson

The character Aitcheson is set to play in X-Men: Apocalypse (2016) is supposedly one of Apocalypse's Four Horsemen. But we know that Storm, Magneto, Psylocke, and Angel will be the Four Horsemen in the new film. However, there's a possibility that more than one version of the Four Horsemen will make an appearance in X-Men: Apocalypse, which opens up the possibility for Fraser Aitcheson to also be in the role of a Horsemen of the Apocalypse.

To reiterate, Aitcheson is set to play a Horsemen, but which is a mystery. There has been a photo released online of Fraser Aitcheson in costume on the set of X-Men: Apocalypse but nothing is discernible from the costume's appearance, other than it looks like the costume of an ancient Horsemen of Apocalypse.

4. Ian Geldart

His role in the film isn't of much importance, but the implications of his character's purpose in the film say more than Geldart will get to say on-screen. Ian Geldart is expected to play the role of a guard in the "Alkali Lake" facility. The Alkali facility is famously known in Marvel Comics' as the location of William Stryker's experimentation programs on mutants, including the Weapon-X program that turned Logan into the Wolverine. William Stryker also has a confirmed role in X-Men: Apocalypse, played by actor, Josh Helman.

Now that we have confirmation of actor, Ian Geldart in the role of a guard at the Alkali facility, it more gives credibility to the theory of a significant portion of the film taking place at Alkali Lake; plausibly even portraying Logan's transformation into the Wolverine. There's already been a tease of Wolverine's return to the franchise in the recently, released trailer for X-Men: Apocalypse.

5. Rochelle Okoye

Okoye is expected to be in the role of someone named 'Plague'. That's most likely a code-name for a mutant in the film, but the more plausible theory is that 'Plague' is another name for one of the Horsemen of the Apocalypse.

6. Monique Ganderton

Ganderton is also expected to be in the role of 'Death' which could coincide with the casting of Rochelle Okoye in the role of 'Plague'. Okoye and Ganderton are likely going to be in the roles of the companion Horsemen alongside Fraser Aitcheson's Horsemen of the Apocalypse. We have a confirmed image of Aitcheson on set of the film in full costume. And that would give us the three of the Four Horsemen whom could be Apocalypse's first incarnation of the deadly team of mutants. Along with the potential of Mister Sinister being cast in the film, it's likely that whichever actor is portraying Mister Sinister/Nathaniel Essex will be the Fourth Horsemen to Apocalypse's first incarnation of the Four Horsemen.
