Ok, let's talk low tech here since I'm not a science dude. During lift off, the rocket is still clearing the tower yet the wives are looking up to what looks like above 60 degrees and crying and so forth. Cut to mission control and then a very cool shot from above the rocket. Then, BAM, close up of Mrs. Lovell looking back down to what seems like just above the tower.
For me, this ruins the whole scene. Swap those two shots and it would have been perfect. I don't see how they could have gotten it so wrong when the rest of the flick is so very good.
