Shane Carruth (born 1972) is an American film writer, director, and actor. He is the writer, director, and co-star of the prize-winning science-fiction film Primer (2004). His second film, Upstream Color, was released in 2013. In recognition of Carruth's idiosyncratic and, at times, bizarre filmmaking, director Steven Soderbergh told Entertainment Weekly, "I view Shane as the illegitimate offspring of David Lynch and James Cameron."
