Superman 1978 Internet Archive !new!
For purists, the 1978 theatrical cut is the only cut. It has the perfect pacing. It doesn't over-explain the magic. Yet, here is the rub: That specific theatrical cut is often buried. Streaming services (like Max, formerly HBO Max) frequently rotate versions. Physical media has been reissued to feature the Donner Cut (for Superman II ) or the extended TV edits.
