Most of the films that are being remade these days don’t need to be, while those that could really use it, generally aren’t.
For instance, Douglass Trumbull’s “Silent Running,” a film about a future Earth that exhausted its resources, is a prime candidate for rebooting because its ‘dying earth’ theme is even more relevant in these days of global warming and environmental degradation.
The movie entirely takes place aboard the ‘Valley Forge,’ one of three space freighters that each hold three huge domes, habitats filled with plants and (small) animals.
Speaking of which, that particular plot point doesn’t really make sense to me because large animals – assuming that they haven’t been killed off – would need conservation as much as smaller ones (which could have been done, though there was no mention of it).
The purpose of the plant life is to re-green an Earth that has undergone some sort of environmental cataclysm.
Freeman Lowell (Bruce Dern, who must have been the Nick Cage of his day) tends to the flora and fauna. He’s there with three other astronauts, and soon the order comes to destroy the habitats that hold the forests, because the freighters that they are attached to are going to be repurposed.
While the others are ready to leave, Lowell is a firm believer in the importance of Nature, and doesn’t want to destroy the habitats. Speaking of which, what doesn’t make sense as to why they are destroying them, when they could easily be put into orbit around Earth (they’re able to detach from the freighters) as opposed to destroying them.
What’s also sort of odd is that despite all the potential for drama, the movie isn’t terribly dramatic, despite the fact that Freeman Lowell murders the rest of the crew.
