The Houston scenes were not filmed in Houston
--- Just because Houston had changed too much in the 25 years between the actual events and the filming is no reason to not show it.

I was lucky enough to hear Jim Lovell speak on the 25 aniversery of Apollo 8, and it was for that mission that he used the line about he and his buddies going to the moon rather than him (Lovell) going on a family trip for Christmas. In the movie they turned that funny line into spring break for the family.
