Those cameras were massive back then, today's filmmakers complain about using 3D cameras which are a fraction of the size of those monsters, imagine their complaints about shooting today if they shot in Todd-AO, truly it was an art form.
They saw the future and they made the Todd-AO version for those curved OLED screens.
