Oh, a deleted scene. Like those which if removed from the film means that never happened. Interesting tidbit though.
Now, let's say it did happen. Can the missile surround Earth several times per second? Because if it can't, then Superman is still able to catch the missile.
Sorry, even if I accept that happened - even when it didn't - it still doesn't explain it.
And that's the point. When it is about millions of innocent people, Superman doesn't make his best effort. When it is about his girl... everything is possible for him. Even going against Jor-El.
See where what some people call 'selfishness' (I call it 'human weakness' or 'fallibility' if you like) in Superman came from? It didn't start with SR. And since SR is based in Donner's vision, it matches.
I know, I haven't said it's not a plothole. I say it as happened all throughout the first two movies and didn't ruin anything for anyone. I don't see your posts complaining about the exact same kind of plotholes in the Miscelanous movies board. Consistency.
