In Iceland, most theatrical projection screens utilizes the cinemascope (2.35:1) aspect ration. But when a standard academy widescreen in projected the image is centred leaving the edges unused. Is that the norm in most countries? What is the de facto theatrical aspect ration in continental Europe and North America?

Maybe John Pytlak knows this.

Hi,

In the UK they're usually 2.35 with motorised side masking.

I know of some that are roll screens and therefore the bottom moves up and down, but that's not really correct - it gives you horrible lens centering issues as the images are then not common centre.

In the states most theaters have 1.85 screens and 2.35 screens. I go to a theater that plays classics and only has 1 screen, and that has a curtain over the screen and they move it back or forward depending on the aspect ratio so that the film takes up the part of the screen that isn't covered by the curtain.

Most cinemas do exactly as you describe. Films are either shot for 1:1.85 (widescreen) or 1:2.35 (anamorphic). The anamorphic ones require an anamorphic lens to project the image, which is squeezed by a ratio of 2:1 on the film itself. Cinema screens have black curtains or tabs which are adjusted to suit the image, so that the edge is defined by the tab itself, not the projected edge of the projector mask.

Many cinemas in Europe, (and some in the US and Australia for that matter) fudge the exact ratio a bit: the 1.85 is often a little taller, closer to 1:1.66, which is sometimes called the "European" widescreen ratio, as it corresponds to the super 16 negative ratio.
