Did we have IMAX in 1983?
The Smithsonian Air and Space museum had IMAX since it opened in the mid 70's. It was impractical to run 35mm feature length films in IMAX venues until this past decade though.
What I meant was the effect at the particular theater I saw Jedi at was IMAX like in the way the screen filled out my field of vision. (Sitting in the sweet spot in the balcony, something modern crackerbox theaters lack.) It made the Speeder Bike chase more intense for me than it has ever been since!
