Fan Casting The Astonishing Ant-Man & The Wasp

Late 1960's. Dr. Hank Pym has discovered a rare group of sub-atomic particles and used them in two formulas. When he tests them on himself, he finds out that he can become smaller and return to his normal size at will, giving birth to a new hero, Ant-Man.

Dr. Vernon van Dyne asks him for help for finding extraterrestial life. Pym refuses at first, but after meeting Vernon's daughter, Janet, decides to help him. The research goes terribly wrong when Vernon gets killed in an accident, caused by Elihas Starr, a rival of both Pym and VanDyne. Janet asks Hank for help to avenge his father. So he gives her some of the formulas he's created, along with a winged suit, giving birth to The Wasp.
