Samuel L. Jackson as Nick Fury
It's the one that says Bad Mother Fricker
Brad Pitt as Captain America/Steve Rodgers
He might be a little old but he fits the roll so well and he can act,
Special FX can fix the age, did you see The Curious Case of Benjamin Button
Anton Yelchin as Bucky/James Barnes
Just look at this kid
Robert Downey Jr. as Iron Man/Tony Stark
Enough said
Don Cheadle as War Machine/James Rupert "Rhodey" Rhodes
Rhodey!
Chris Hemsworth as Thor/Donald Blake
He made a good George Kirk even if it was only for 5 minutes, his size bothered me at first but im sure he will pack on the muscle
Edward Norton as The Hulk/Bruce Banner
Im hoping he will return for The Avengers
Scarlett Johansson as Black Widow/Natalia Alianovna Romanova(a.k.a.Natasha Romanoff)
Who doesn't like looking at her
Cillian Murphy as Giant-Man/Henry "Hank" Pym
He would have to beef up a little bit, but he is a good actor and looks smart enough to be a scientist
Natalie Portman as The Wasp/Janet van Dyne
I know she is playing Jane Foster in the Thor movie I just think she would be great for this part
Jeremy Renner as Hawkeye/Clint Barton
This guy is a pretty decent actor so I think he would be great in a supporting role like this
Milla Jovovich as Scarlet Witch/Wanda Maximoff
Jensen Ackles as Quicksilver/Pietro Django Maximoff
Everyone wants this guy to play Captain America but I dont think he has paid his dues yet, He looks more like a Quicksilver to me anyways
Liam Neeson(Voice)/Doug Jones(Special FX) as Vison
Liam Neeson just has that voice, he voiced Aslan in Narnia for crying out loud
Djimon Hounsou as Black Panther/T'Challa
This man was made for this part
Elisha Cuthbert as Ms. Marvel/Carol Susan Jane Danvers
I have been in love with this girl since 24
Will Smith as Falcon/Samuel "Snap" Thomas Wilson
He has already played this character pretty much except it was called Hancock
Zachary Quinto as Namor/Namor McKenzie
Thanks to Star Trek we already know he looks good in pointy ears
Gerard Butler as Hercules/Heracles(a.k.a. Harry Cleese)
300 Need I say more?
Clive Owen as Doctor Strange/Dr. Stephen Strange
Just thought this was a great match
Tyrese Gibson as Luke Cage a.k.a The Power Man/Carl Lucas
William Hurt as General Thadeus "Thunderbolt" Ross
Tom Hiddleston as Loki
Til Schweiger as Red Skull/Johann Shmidt
He is German and a good actor he could pull it off
Jet Li as Mandarin
