The cast of Marvel's Ant-Man and the Wasp just grew by one. According to Variety, Black Mirror actress Hannah John-Kamen has joined the film in an as-yet-unannounced role.

Though not much is known about the upcoming Marvel Cinematic Universe installment, it seems as though the film is gearing up for production; just last month, star Evangeline Lily revealed that she recently had a fitting for her Wasp costume. However, aside from the fact that the film will feature some new suits and gadgets, most details about Ant-Man and the Wasp are being kept under wraps for now.
