GoKawiiliPhone-style folding Duo device matches IMAX 1.43:1 ratio of Nolan's 'Odyssey'
A folding dual-screen phone concept called the iPhone Duo has an aspect ratio nearly identical to IMAX 70mm's 1.43:1 format, the same shape used to film Christopher Nolan's 'The Odyssey.' Since only 41 theaters worldwide can show the film in its full IMAX ratio, most viewers saw up to 40% less image than intended, cropped at top and bottom in standard theaters.
