Fan Casting Black Knight in Edgar Wright's Astonishing Ant-Man

Nathan Garrett was a young civil engineer with a gambling problem who had gotten in over his head with one of his bookies. Threatened with death after being unable to pay, Garrett was approached by the Crimson Cowl who agreed to pay off all his debts in exchange for his services. The Cowl provided Garrett with his initial laboratory and workshop, which he used to manufacture his first power lance and mutate a horse to possess functioning wings. Disobeying the Crimson Cowl's orders, Garrett donned the guise of the Black Knight in order to "field test" the equipment. This first outing brought him into conflict with Ant-Man and Wasp, and he was arrested. The Cowl arranged for Garrett to be freed on bail, but he insisted on going out again to "settle the score" with the Diminutive Duo. Once again, he was defeated and sent to jail. This time, however, the Cowl refused to post his bail. Garrett was, however, broken out of jail weeks later by the Asgardian known as the Executioner on behalf of Baron Zemo, and invited to join Zemo's group, the Masters of the World. As a member of the Masters, the Black Knight fought the Avengers, of whom Ant-Man and Wasp are members, but was captured and sent back to prison. The Black Knight is currently in prison, but for how long is anyone's guess.
