a/ What aspect ratio were Kubricks films shown in theatrically?
“2001,” was Super Panavision and should be shown in 2.20:1 in a 70mm print. “Spartacus” was Super Technirama, which was 2.35:1 in the 35mm prints, but might have been cropped to 2.20:1 in the 70mm prints. “Barry Lyndon,” was released theatrically in 1.66:1, even in the U.S. since Kubrick insisted on 1.66 hard mattes being sent to the various theatres showing the film (1.85 is the common “flat” widescreen ratio in the U.S.). “Dr. Strangelove,” was released in home video in Kubrick’s preferred “multiple aspect ratio” but there is no way it could have been shown that way theatrically since you cannot change projector mattes in mid-screening (although it could be shown in Academy 1.37 and various hard mattes could appear in the image, cropping it to 1.66 at times — however, Academy 1.37 had pretty much become obsolete as a projection format in most theatres by the 1960’s.) I saw it projected to 1.
