For this fancast I've casted characters who I'd like to see in a movie and who'd I like to see play them, though some characters were left out due to not finding an actor I was happy with, e.g. Colossus, or seemed to fit better in a sequel, e.g. Kitty Pryde.
FANCAST - X-Men
Professor Charles Xavier - Hugh Laurie 52 6'2.5" (House, Stuart Little)
The one and only choice in my opinion.
Logan/Wolverine - Tom Hardy 33 5'10" (Inception, Layer Cake)
One of my favourite actors and I have seen him suggested for this role before and I do believe he would absolutely destroy as Wolverine.
Scott Summers/Cyclops - Matt Bomer 33 5'11.5" (White Collar, The Texas Chainsaw Massacre: The Beginning)
My favourite X-Man. I may have seen this casting before I'm not sure, but this guy deserves a chance to be in mainstream movies, he is a good actor and I think he'd do great as the team leader of the X-Men, Cyclops.
Jean Grey - Yvonne Strahovski 29 5'9.25" (Chuck, Mass Effect 2)
Incredibly attractive and not a bad actress, need I say more.
Bobby Drake/Iceman - Garrett Hedlund 26 6'2.5" (TRON:Legacy, Death Sentence)
A good up-and-coming actor, who deserves more big roles, and due to the continued debate on whether Iceman should be young or older I've gone with an inbetween.
Ororo Munroe/Storm - Angell Conwell 28 5'4" (Soul Plane, Baby Boy)
Actually saw this actress in JacobCityBros all-Black Spider-Man fancast and thought she looked like she could do a good Storm.
Hank McCoy/Beast - Jon Hamm 40 6'0.5" (Mad Men, The Town)
A fan favourite for the role and a clearly talented actor.
Warren Worthington III/Angel - Armie Hammer 24 6'5" (The Social Network, Blackout)
Another fan favourite for the role, second only to Alex Pettyfer and I chose Hammer over him because Angel is supposed to look like the perfect human and lets face it Hammer is tall, handsome and looks like he could pack a punch.
Kurt Wagner/Nightcrawler - David Tennant 40 6'1" (Harry Potter and the Goblet of Fire, Doctor Who)
Tennant is an amazingly talented actor and I believe he could do Nightcrawler down to the T.
Brotherhood of Mutants
Erik Lensherr/Magneto - Christoph Waltz 54 5'8.5" (Inglourious Basterds, The Green Hornet)
Despite his size I'd say he was perfect for the role but I still believe he could find a way to make his Magneto as memorable as he was as Hans Landa.
Raven Darkholme/Mystique - Rhona Mitra 35 5'7" (Shooter, Hollow Man)
Talented actress, attractive and can kick butt.
St. John Allardyce/Pyro - Kevin Pennington 24 6' (Miss March, Spring Breakdown)
Don't actually know much about this actor only seen Miss March with him in it, but I saw him as one of the choices in SuperDude001's X-Men poll fancast, and just thought he looked like he'd be good as Pyro.
Sabertooth - Richard Armitage 39 6'2" (Captain America: The First Avenger, Robin Hood)
A good actor and if he buffed up dyed his hair blonde and grew Sabertooths muttonchops, we'd have a pretty damn good Sabertooth.
Mortimer Toynbee/Toad - Jackie Earle Haley 50 5'5.5" (Watchmen, Shutter Island)
Unoriginal, I know, but I just think he'd be great as Toad.
Other
Senator Robert Kelly - Bill Nighy 61 6'2" (Harry Potter and the Deathly Hallows: Part 1, Hott Fuzz)
Bill Nighy is a great actor and could easily get us to despise him as Senator Kelly.
