Before IMAX came Cinema USA – Central Pier

 

Taken in 1981 this shows the Cinema USA dome.
Inside, a film was shown with the normal eye-line way above the normal horizon. There were no seats so you stood looking upwards which threw you off balance a bit to start with. The films were of the fast motion variety – a ride in a Porsche, a roller coaster ride, a helicopter over a gorge etc. People would sway or even lurch sideways watching the film. I seem to remember the odd one in 3D too. They were a pre-cursor to Imax.

It is now the site of a Big Wheel.
