Last night, we showed you the first image of the Cosmic Cube in Captain America: The First Avenger.  Today, concept art of the film's villain, Red Skull (played by Hugo Weaving), may have leaked online.  The artwork is of a similar style to the concept art of Captain America that appeared online last June.  If this is indeed what the Red Skull will look like in the film, I'm a little surprised that the costume looks slightly futuristic.  The movie is set during World War II, but Red Skull looks like he's a Nazi of the future.  Of course, even if this is official concept art, it's possible that this was just a proposed design that won't appear in the final film.Hit the jump to check out the concept art.  Directed by Joe Johnston, Captain America: The First Avenger stars Chris Evans, Hayley Atwell, Sebastian Stan, and Tommy Lee Jones.  It opens in 3D on July 22nd.Image via MundoHype via DailyBlam:captain-america-the-first-avenger-concept-art-red-skull-01And for those just tuning in, here's the official synopsis for Captain America: The First Avenger:

Marvel Studios’ Kevin Feige will produce CAPTAIN AMERICA: THE FIRST AVENGER. Alan Fine, Stan Lee, David Maisel and Louis D’Esposito will executive produce. The film will be released in the US on July 22, 2011 and distributed by Paramount Pictures.

CAPTAIN AMERICA: THE FIRST AVENGER will focus on the early days of the Marvel Universe when Steve Rogers volunteers to participate in an experimental program that turns him into the Super Soldier known as Captain America.

Born during the Great Depression, Steve Rogers grew up a frail youth in a poor family. Horrified by the newsreel footage of the Nazis in Europe, Rogers was inspired to enlist in the army. However, because of his frailty and sickness, he was rejected. Overhearing the boy’s earnest plea, General Chester Phillips offered Rogers the opportunity to take part in a special experiment… Operation: Rebirth. After weeks of tests, Rogers was at last administered the Super-Solider Serum and bombarded by “vita-rays.” Steve Rogers emerged from the treatment with a body as perfect as a body can be and still be human. Rogers was then put through an intensive physical and tactical training program. Three months later, he was given his first assignment as Captain America. Armed with his indestructible shield and battle savvy, Captain America has continued his war against evil both as a sentinel of liberty and as leader of the Avengers.
