Is 70mm the same as IMAX

Contradicted by strong evidence

What we can confirm

IMAX is a proprietary large‑format cinema system that can use a special horizontal 70mm film format (IMAX 15/70), but standard 70mm film presentations and IMAX are not the same; IMAX involves distinct film geometry, projection technology, screen design, and sound, and not all 70mm screenings are IMAX and not all IMAX screenings use 70mm film.
