Good Science Movies

Our Benevolent Seed Overlords ask:

What movie do you think does something admirable (though not necessarily accurate) regarding science? Bonus points for answering whether the chosen movie is any good generally....

Here's my list (which I might update):

1) Apollo 13. The heroes aren't the big, famous stars. The heros are the nerds. They don't beat someone up to save the day, or roar in inchoate rage like Mel Gibson, they use reason and logic to solve the problem.
2) From The Earth to the Moon (#15). It's not technically a movie, but it shows how the Apollo astronauts were taught to be geologists.
3) GATTACA. The first and last fifteen minutes are superb. A good film about genetic determinism (and a beautiful set too).

Now if only someone would make a movie version of Arrowsmith...
