Laser IMAX is a format I’m very excited about, generally because I love a big film showing in IMAX that’s been shot with IMAX cameras (or at least partially in IMAX), but while most recent modern films are shot in digital IMAX, they only have a widescreen aspect ratio that opens up to around 1.89:1, while IMAX footage shot on film can open right up to 1.44:1 – but that’s only as long as the cinema supports it.
