I was among the members of the press invited last September to the Atlanta set of Marvel’s Ant-Man and the Wasp. While the filmmakers and cast were understandably guarded about discussing certain aspects of the film, they did reveal some key new details, particularly about the Quantum Realm.
There was one character in particular that proved nearly impossible to get much information about: the film’s antagonist Ghost, played by Tomb Raider and Ready Player One actress Hannah John-Kamen.
In the Marvel Comics, Ghost wore a specially designed suit that allows him — yes, the character was male in the books but has been changed to female in the movie — to phase through walls or become invisible. Ghost uses those abilities to commit acts of corporate espionage and terrorism, with the goal of punishing businessmen who abuse their wealth. But what of her motivations in the movie? No one would say.
