Men in black have always protected the Earth. In this new adventure, they are facing the greatest threat so far. Tessa Thompson is trying to erase memories and wants to track down the agency. She’s associated with Chris Hemsworth. In the film are used top machines, and futuristic laser weapons appear a hammer that Agent H throws. The inclusion of the Neuralyzer in the trailer is a nice nostalgic touch, though a surprising one given its importance in the original trilogy. It includes the neuralyzer, the memory-erasing device used for witnesses to forget about alien agents and life forms.
