Lion Force Voltron (Voltron of the Far Universe)
Over view:
Voltron features a team of five young pilots commanding five robot lions which can be combined to form Voltron. In this undefined future era, the Voltron Force is in charge of protecting the planet Arus (ruled by Princess Allura) from the evil King Zarkon (from planet Doom), his son Lotor, and the witch Haggar, who would create huge Robeasts to terrorize the people of Arus.
This is a live-action fancast for the upcoming Voltron movie. Everything would remain faithful to the original series however I would change the uniform colors around and have the uniforms of the five pilots reflect the color of the lion they pilot. It always drove me nuts that Keith was pilot of black lion but had a red uniform; with that said here is my fancast.
KEITH:RYAN KENNEDY
Ryan played a similar role on Smallville as cosmic boy leader of the legion. I think he would have more commanding presence with more screen time.
LANCE:CHANCE CRAWFORD
Lance is the hot head of the group with a Cocky attitude. I think Chance Crawford could play the part well and he looks like the character.
HUNK:KELLAN LUTZ
Hunk is the strong man of the team and Kellan Lutz is perfect for the role he is a favorite for He-Man but I think he would fit better with Voltron and the character of Hunk.
PIDGE:ANTON YELCHIN
Antons performance in STAR TREK is what I would see a young Pidge acting like; he has the talent to bring the character to life.
SVEN:HAYDEN CHRISTENSEN
Who better to play the character of Sven with a doomed ending than Darth Vader himself;Hayden would be an awesome Sven his loss would be a tragic one and I could see him really bringing that out on screen.
PRINCESS ALLURA:RACHEL NICHOLS
Rachel was decent in G.I. JOE and proves she has fighting skills when needed I can see her owning the role of Allura and defending the people of Arus proudly.
KORAN:JEREMY IRONS
Koran the trusted guardian of Allura; Jeremy Irons is perfect at being a mentor figure and protector all at the same time it would be interesting if he would have some action scenes as well.
The Villains...
ZARKON:TIM CURRY
Tim Curry is one of my favorite actors he was dark and sinister as the lord of darkness in the movie LEGEND and would bring the same type of performance if not better to King Zarkon.
LOTOR:LUKE GOSS
Prince Lotor is a hard one to cast because a lot of people want Orlando Bloom however I think Luke Goss would be a better choice his character of the prince in Hellboy 2 reminded me of Lotor plus he also has the martial arts & sword skills down pact.
HAGGAR THE WITCH:HELENA BONHAM CARTER
She is another favorite actress of mine and I use her a lot for dark characters but with good reason because she can take a secondary character and bring it to life and own the screen with just a short amount of time she would own the role of Haggar.
