I think the SFX for this movie were very realistic for the time and still stand up very well. .
Except for the part when an Aquarius/Odyssey rocket the size of Cuba is shown with the Moon and Earth in the same shot.![]()
Which scene is that, cause I have never noticed it before, and I love seeing that kind of stuff.
And yes I agree with everyone here that Apollo 13 is a great great film, and certainly holds up to repeat viewings.
