Here's Seed, a starkly handsome short film inspired heavily by 1960s and 1970s science fiction cinema. Explains director Tyson Wade Johnston, "Set in the year 2071, where technology has brought mankind to the brink of colonization on a planet named Gaia, one astronaut takes on an isolated mission and discovers unearthly horrors that could bring an end to human life on this planet." Also check out his prior short flick, the creepy alien invasion film Exist. Hat tip to Davis!
