I love concept art books because you can see the evolution of a design and see all the roads not taken.  A big production like The Amazing Spider-Man goes through thousands of designs as artists draw out their ideas for the sets, costumes, creatures, props, and other good stuff.  Today, some unused costume designs and concept art has landed online.  The costumes design is fascinating because one costume is remarkably similar to the outfit from Sam Raimi's Spider-Man trilogy, and the other two are radically different from anything we've seen (especially the mask and spider emblem).  As for the concept art, it's a different look at the Lizard, and while I'm not sure if it would have translated to a three-dimensional model, I like that it looks less humanoid than the final version.

Here's the official synopsis for The Amazing Spider-Man:

One of the world’s most popular characters is back on the big screen as a new chapter in the Spider-Man legacy is revealed in The Amazing Spider-Man. Focusing on an untold story that tells a different side of the Peter Parker story, the new film stars Andrew Garfield, Emma Stone, Rhys Ifans, Denis Leary, Campbell Scott, Irrfan Khan, with Martin Sheen and Sally Field. The film is directed by Marc Webb from a screenplay written by James Vanderbilt, based on the Marvel Comic Book by Stan Lee and Steve Ditko. Laura Ziskin, Avi Arad, and Matt Tolmach are producing the film in association with Marvel Entertainment for Columbia Pictures, which will open in theaters everywhere in 3D on July 3, 2012.

The Amazing Spider-Man is the story of Peter Parker (Garfield), an outcast high schooler who was abandoned by his parents as a boy, leaving him to be raised by his Uncle Ben (Sheen) and Aunt May (Field). Like most teenagers, Peter is trying to figure out who he is and how he got to be the person he is today. Peter is also finding his way with his first high school crush, Gwen Stacy (Stone), and together, they struggle with love, commitment, and secrets. As Peter discovers a mysterious briefcase that belonged to his father, he begins a quest to understand his parents’ disappearance – leading him directly to Oscorp and the lab of Dr. Curt Connors (Ifans), his father’s former partner. As Spider-Man is set on a collision course with Connors’ alter-ego, The Lizard, Peter will make life-altering choices to use his powers and shape his destiny to become a hero.
