9D Cinema, Philadelphia

9D Cinema might sound like a movie theater, but its 6- to 14-minute shows are as much of a ride as they are a movie. Patrons recline in active-motion seats that tilt and shift to match each movie's events, creating a viewing experience more immersive than just moving your legs up and down while an action hero runs onscreen. While the seats swivel about, special effects stimulate film-appropriate weather. The theatre might turn snowy and windy for a film such as Polar Region Hurricane; on the other hand, during a spooky film such as Ghost House, it might be illuminated by a carefully timed lightning bolt.
