VOLTRON Rumor: Henry Cavill's Role Revealed As First Plot Details Tease Battle Between Team Voltron And Zarkon

The upcoming Voltron movie wrapped filming last summer, and we've yet to see so much as a single still from the live-action adaptation. Still, excitement among fans for this adaptation of the 1980s animated TV series Voltron, Defender of the Universe, is understandably high.

For those of you unfamiliar with the premise, Voltron revolves around five piloted Robot Lions that can combine to form the ultimate humanoid robot, Voltron, to battle evil. Filmmaker Rawson Marshall Thurber (Red Notice, Skyscraper) has said his take will "stay true to the heart and the spirit of Voltron" while "introducing an entirely new generation of pilots."

It's a project with plenty of potential, even though it's always hard to please longtime fans of a property like this one (with any luck, Voltron will fare a little better than the Transformers movies). 

Feature First (via SFFGazette.com) has shared some new details about the movie today, including the first plot details:

"After his mother’s death, a grieving Earth teen uncovers a devastating truth: she was a legendary Voltron pilot from Altea, secretly protecting the galaxy. When the tyrant Zarkon breaks free from imprisonment and launches a brutal assault on Altea, the grieving boy is thrust into her legacy—forced to pilot her lion and reunite Team Voltron."

"But haunted by self-doubt and repeated failures, he struggles to measure up… until he realises her true strength wasn’t in skill or tech, but in courage forged through loss. In order to save Altea—and honor her—he must find that same fire within himself."

The site is also claiming that Man of Steel star Henry Cavill has been cast as the King of Altea, with Sterling K. Brown (Black Panther) set to play Voltron's big bad as Zarkon (a role he's been attached to for a while now). 

Daniel Quinn-Toye is playing the teenager mentioned in the description above, while the cast is rounded out by Rita Ora, John Harlan Kim, Alba Baptista, Samson Kayo, Tharanya Tharan, Laura Gordon, Tim Griffin, and Nathan Jones.

Teasing the movie last year, Brown said, "Rawson Marshall Thurber is the director, the screenwriter. I think he’s come up with a really wonderful vision to reintroduce something that we grew up with in the ’80s to the 2027 crowd."

“It’s heartfelt. It is big. It’s big, bodacious and dynamic, and that’s why it takes probably about 48 weeks of post-production to finish the thing off and get it together. I think things will be wildly entertaining," the actor continued, adding, "God-willing, we’ll get the chance to do another one."

The Voltron movie is expected to arrive exclusively on Prime Video in 2026.

the transformers movies get too much flack. the plot points might be stupid in those sequels, but they are visually spectacular, paced well, fun casts. michael bay knows what he is doing!
this will be slop, because everything nowadays is just story-telling, nobody knows how to frame or light a good looking shot or how to put a script to screen in a way that is interesting. nobody has any new ideas or cares to put the effort into making something feel fresh. just a bunch of talking heads, exposition, and poorly framed cgi eyesores. this will be absolutely no different from all the terrible shows and movies of the last 15 years that scoff at transformers while trying to recreate them.

sorry for the rant, I just hate the josh's comment that this has potential to be better than transformers. no it wont! nothing about it will be original in any way! and it will look like shit!

@nibs - I'm old enough and nerd enough to have watched the original shows (Transformers and Voltron) whey they first aired. They were more or less contemporary. I'm not sure I follow why Michael Bay' films will necessarily be superior to this adaptation. We haven't seen anything yet. And I found Michael Bay's adaptations extremely underwhelming. The Bumblebee film was by far better, probably because Bay didn't direct.

@dragon316 - fans need stop over thinking things with transformers and comic book plot story always remain same plot and story is shown in trailers if you see enough comic entertainment read enough comic entertainment you will know what transformers and comic book movies are all about before teaser trailers are even released to public it’s very obvious answer

@dragon316 - comic books and transformers are NOT work of art such as Scarface , and other movies that have won awards there entertainment called entertainment for reason all movies tv shows label entertainment if you know theme of certain entertainment transformers and comic books you know what story and plot is all about you do not know what characters are in it but story plot remain same always stop acting like non paid movie critic you will figure that out eventually

@TheVisionary25 - King Alfor was the blue lions pilot father, Princess Allura(I’m sure there’s an easier way I could’ve said that). Princess Allura is who I assumed was the fallen pilot whose son is in the synopsis.
And I think Cavill is playing Keith (The Black Lion pilot), I guess if he married Princess Allura that he would be king Altea.

It sounds like the kid is Princess Allura's kid. Keith the dad, maybe?

On one had, I'm glad they aren't just doing a revisit with the original cast at this point. There's been quite a lot done with them. On the other, the plot sounds kind of aligned with He-Man's rumored plot. 80's property person on earth has connection to a distant world and has to go back and save it.

I don't have much hope for this. My 2 favorites from when I was a kid was Voltron and GI Joe (more the comic book). They royally screwed up GI Joe every step of the way. Snake Eyes would have been so easy to follow a bit more closely the comic storyline. The original snake eyes run from like Silent Interlude on through Storm Shadow's redemption is gold.

@EVH - Same. I loved, LOVED, Voltron as a kid, so I hope this is awesome. Cavil should play Keith but is the Princess dead now?

@EVH - that’s exactly who I think the kid is. I think Cavill is playing Keith also.

The synopsis is nice if true!!.

Im not too familiar with Voltron lore throughout its different iterations but I guess if Henry is the King of Altea , that likely means he is playing King Alfor…

Also , Sterling K Brown as the villain Zarkon is pretty good casting!!.

Anyway , I hope this turns out well but Rawson Marshall Thurber gives me pause since I haven’t liked his films that I’ve seen recently such as Skyscraper & Red Notice.

I LOVED the Netflix series. Shit was sooooo good so hoping they take some inspiration from that show. Ill definitely give this a watch becuz I like voltron and a big cavill fan... but doubt it'll be that. Hope to be pleasantly surprised

@MotherGooseUPus - I really enjoyed the series but thought seasons 6 and 7 were a bit disappointing.

I grew up with Voltron and ive generally enjoyed each version to doke degree, whether it was the original, cgi show of the 90s, the kiddie cartoon show in the early 2010s to the Netflix show, can’t wait for this movie. I like how it’s not just a remake and it’s a continuation. I’ve heard some speculation and hope i find it entertaining. Hoping Cavill shines in it but I’ve read that the first cut of the movie, he’s not in it much. Also hoping it’s in the movies and not just streaming.

I hope that the movie has heart and we actually care for the human characters, instead of brushing past it and focusing solely on giant robots.

So they're killing off Allura...? I have to endure that again?
