The exhaust flames weren't CG from what I understood, though I have no idea how they actually did it. Looks very nifty, though =D>

More nitpicks, mostly from the launch sequence:

* During launch, the F-1 engines were covered in asbestos insulation with a foil-like "batted" covering. The insulation was missing in the movie.

* I'm not certain about this, but doesn't the BPC cover the hatch window?

* BPC jettison is reported by the CapCom well before Tom Hanks says "tower jet"

* There's a slight delay between the line "SECO" and the engine cut-off being shown. (yeah, I know this is just whining, but I notice it, ok)

* In the "dream" where Tom Hanks is bouncing around on the moon, there's an unmistakable swirl of dust around his footsteps. Guess they should've shot that scene in a vacuum chamber...

And a last one:

* Fred Haise didn't chew bubblegum :P
