Silent Running ★★½

A sci-fi take on the 70's environmental issues gone wild. The movie doesn't make a lot sense but was unique for the time. I still enjoy the ship and space EFX. It was amazing how the drones were created and brought to life. While the story is slow Bruce Dern does an excellent job in the lead and the supporting cast of Cliff Potts, Ron Rifkin and Jesse Vint are solid.
