The attack by the Titans

A man in a brown jacket leans against a quilted surface in a dimly lit room, then the scene cuts to a test pattern. A muscular figure with short blonde hair stands against a bright blue sky, then runs forward with a determined expression. The view shifts to a low angle of a horse's legs galloping across a wooden bridge, followed by a close-up of a red, muscular leg moving through the air. The sequence ends with a rear view of a person in a white outfit running across a sky filled with clouds.
