Wondering around the AGO I stumbled upon this interesting tabloid describing the sci-fi genre according to Robert Smithson:
“…Robert Smithson used filmmaking as a form of expression and as a link to the remote locations of his earthworks. His wife Nancy Holt was a creative partner in many of his cinematic works. A devoted film buff, Smithson believed science-fiction movies reflected people’s anxieties about the role of humans on the planet.”
