IMAX is neither the first nor the only film format to incorporate the concept of a variable aspect ratio. Filmmakers have toyed with the shape of their projected images at least as far back as Abel Gance’s 1927 silent epic Napoléon.
In a separate post, I maintain a list of movies that alternate from a widescreen 2.35:1 aspect ratio in some scenes to other shots with a taller height, as they appeared in IMAX theaters. The purpose of the list on this page is to document other films, unrelated to IMAX, that also change the shape of the displayed image from scene to scene, but perhaps in different ways.
This list will be updated as needed.
Notes
- “CIH” = Constant Image Height.
