It begins with two agents - ominous, shades-wearing - at the end of a long, white corridor. We pull back behind an air vent to reveal... Ant-Man, tiny as they come, sporting a red-and-black suit, with a mask that's a nod to the original Kirby design.
He then jumps through the vent, runs along the corridor and zaps to normal size. The agents draw their guns. Ant-Man changes back and leaps INTO the mouth of one of the agents, knocking him out. He then grabs the tie of the other and flips him through the window. Agents dealt with, he changes back to normal size, enters an elevator and then zaps back down again.
It looked great, despite the fact that it was an unfinished test (when we saw normal-sized Ant-Man, it was a stuntman in a warehouse on wires), but it had plenty of Wright's trademark kineticism. "It's action-packed," he quipped. "Ant-Man will kick your ass, an inch at a time."
