Fact: Edgar Wright requested Marvel (recently bought out by Disney), to refrain from using Ant Man and the Wasp in their motion pictures. Due to this agreement, Ant-Man was not played in The Avengers (2012).
Ant Man marvel comics motion picture is about a con-man by the name of Scott Lang (played by Paul Rudd) who has the astonishing ability to shrink in scale but increases with power. Scott Lang must embrace his inner morality and help his mentor, Dr. Hank Pym, the original Ant-Man, protect the secrets behind his spectacular suit from new threats.
The original movie was supposed to focus around Hank Pym, the original Ant-Man. The problem with this was that filmmakers deemed Pym had too much family-unfriendly history. Why so? Pym developed split personalities, one of which abused his girlfriend Janet. So the filmmaker decided to focus on his successor, Scott Lang, while Pym became a mentor.
The movie was in the works back in 2003 when director Edgar Wright proposed the film to Marvel. He had been testing this idea since then, even going as far as shooting test reels and hiring cast. Suddenly, he dropped out due to “creative differences” between him and Disney that recently purchased Marvel in 2014.
Peyton Reed would end up directing the movie. But during that 11 year stint, Edgar Wright asked Marvel to keep the film out of other superhero motion pictures until ant man movie release date was agreed upon and was within close proximal time.
