Ant-Man and the Wasp director Peyton Reed wasn't a big fan of Yellowjacket, the first movie's villain, but that motivated him to go in a brand new direction for the sequel.
Reed inherited Ant-Man after director Edgar Wright exited the project due to creative differences. Although he loved Wright and co-writer Joe Cornish's premise of a heist movie, he was less thrilled with the villain that was already established in the project.
"The villain in that movie felt like a bit of a vestige from the era in which that project was started, [which was] around the time of Iron Man one, where you have an antagonist who has a similar power set [as the hero]," Reed told io9. "I was hell bent on doing something different in [Ant-Man and the Wasp]."
With more time to develop the story, Reed found his Ant-Man and the Wasp antagonist in Ghost (Hannah John-Kamen), a dimension-shifting villain who is after the quantum technology developed by Hank Pym and Hope Van Dyne. The pair ends up needing Scott Lang's help to explore the Quantum Realm, which could be difficult since Scott is under house arrest following the events of Captain America: Civil War.
In theaters this Friday, Ant-Man and the Wasp stars Paul Rudd, Evangeline Lilly, Bobby Cannavale, Michael Peña, Tip “T.I.” Harris, Judy Greer, David Dastmalchian, Michael Douglas, Michelle Pfeiffer, Laurence Fishburne, Hannah John-Kamen, Randall Park and Walton Goggins.
