I just got a copy of the DVD of the live action movie two days ago (scored it off eBay cheaply) and watched it. My Japanese is VERY rusty but I was surprised how poorly delivered the lines by clearly American actors were. Buzz Aldrin does a cameo, of himself... in 2025? Yeah, that seemed quite odd as he'll be almost pushing 100 by then, but not nearly as odd as how he delivered his lines. I know he's not an actor, but his appearance in the Transformers movie was 'King Lear' compared to this, and it was more the writing. I can't believe he didn't see the lines and said to someone, "You realize no English speaker talks like this".
Great FX shots of the launches, you really believe it when you see them. The plot is not that big a deal and there are some gravity issues on the Moon scenes (and how nobody can seem to simulate a pressurzed space suit in movies), but all the hardware is quite believable and they clearly had full NASA cooperation.
I hope there'll be a dubbed version on DVD eventually, as I know an English version does exist already.
