What are the 'green' sci fi movies?
I'm thinking a couple of Star Trek movies, the one with the Genesis device and the one with the whales (III and IV?).
And I'm thinking of Avatar.
And that one from the 70's with the greenhouse in space, Logan's Run?
That odd one with Hugh Jackman, that kind of mystical Buddhist green house one.
What else? I'm thinking there's more, but I'm blank on it.
