The only film that I can think of with authentic aspect-ratio chnages is Douglas Trumbull's "Brainscan". In it's original release, the "brainscan" sequences were in 70mm while the narrative proper was in 35mm. My memory is foggy on this but I think the 70mm was in 'scope while the remainder of the film was 1.85..At any rate, this must have been a nightmare for projectionists.... There are other films which include varied ratios for more obvious reasons, like "That's Entertainment", or the opening scenes of "Superman" amd "Popeye". Two other scenes that toy with screen size in different ways but are probably worth mentioning: "Will Success Spoil Rock Hunter?" begins with Tony Randall "opening" the frame to its approproate Cinemascope dimensions... and finally, "Finian's Rainbow",which was reportedly released in a wider format that it was shot, resulting in the omission of Fred Astaire's feet during the dance numbers..... And speaking of aspect ratio, for years I've been giving students my standard anti-letterboxing lecture, but I'm wondering if anyone can offer fresh examples of how an altered aspect ratio damages or changes film content, perspective, etc....
