Transformers

Two men stand in a sunlit auto repair lot, one in a patterned shirt and hat, the other in a t-shirt, as the man in the hat gestures with his right hand toward the other man. The scene shifts to a massive robot falling through the air above a city, then to a bright white flash, followed by a woman inside a vehicle looking up in alarm, then a bus driving on a highway, and finally a large bus being attacked by a mechanical creature on a road.
