90% of the time, when movies are shot 1.33 and cropped to 1.85 or so, it was intended that way. 1.85 movies, if I recall, aren't anamorphic on film, they actually ARE 1.33 images cropped, and that's the way they're shot. Some movies are "soft"-matted, which means that the entire 1.33 frame is shot, but when they are filming, on the monitors and such the top and bottom are covered. So when the film is released in 1.33 "full" frame, when the frame is uncovered, it is NOT how it was intended to be originally, and there can be boom mikes in frame, etc that aren't visible in the widescreen image. So, if a widescreen version exists, 90% of the time, even if the fullframe version shows more, the widescreen version is the intended version. The only exception I can think of off the top of my head is THE EVIL DEAD, which, on the newest DVD (with a DTS soundtrack) was cropped to 1.85 under Sam Raimi's supervision, but it was not how it was originally intended (fullframe).
