The Theaters

  • Rectangular Big Movie screens are generally five to eight stories high (55 to 80 feet), or up to 4500 times bigger than the average TV screen. An IMAX® screen in Sydney, Australia, is 96.9 feet high (almost 10 stories, or 30 meters high) and is considered to be the world's biggest movie screen.

  • While most screens are rectangular (flat), and situated entirely in front of the viewer, other Big Movie screens wrap around the viewer in the shape of a 'dome.' As large as 99 feet in diameter (30 meters), dome theaters are shaped like a bowl (parabolic), and many utilize a "planetarium star field projector."

  • Up until recently, IMAX Dome theaters were called "OMNIMAX" instead of "IMAX," though they were both made by IMAX Corporation. However, in recent years many "OMNIMAX" theaters have been renamed "IMAX Dome" theaters.

  • Of the world's 300 Big Movie theaters, about 200 are flat screens and 100 are domes. 110 have the world's most advanced 3-D capabilities. (Except for one experimental domed-3D theater, all 3-D screens are flat.)

  • There are thousands of tiny holes spaced evenly around the screen to permit the sound to travel directly toward the audience, giving the screen 'acoustical transparency.'

  • The screen is painted by a robot to ensure an even coating of highly reflective paint.

  • On average, 28 pounds of refuse are collected after each screening.

  • Some Big Movie screens are large enough to show a whale "life-size".

  • The screens are made of Perforated Stretched Vinyl.

  • Screens can weigh over 800 pounds.
