5. No artist creates in a vacuum, and writer/director Johnson readily admits he was influenced by other films, including "Twelve Monkeys" (1995), "Blade Runner" (1982), and "Akira" (1988). However, in an exclusive interview with Yahoo! Movies (which we're posting next week due to multiple spoilers), Johnson notes that "Looper" was most influenced by a seemingly unlikely film: "Witness" (1985), which tensely depicts Harrison Ford going undercover in Amish country to protect a young boy. "I'm a huge fan of the movie 'Witness' and that back half of the script, especially when I was writing, the way that they sustain the tension in that movie even when they're out on the farm is something that I directly looked to for the back half of this," says Johnson.
