Here’s an example of a scene with alternate takes and angles used. Some trims and alterations to the timing have been made to keep things in sync.
Hi, this is my first post on this website. I’ve been researching the Superman saga for a while now, and I thought I’d fill you in. The alternate camera angles of Zod in the TV version are the same ones that appeared in the Lester theatrical release. The majority of that scene was shot by Donner in 1977, but in order to receive full credit on the film, Lester reshot several scenes that Donner already filmed. Note how the background behind Zod is different in Lester’s version. It wasn’t until the Donner cut that this scene was restored to its original form without Lester’s refilmed close ups.
