"Predestination, adapted from sci-fi author Robert A. Heinlein’s 1959 short story "—All You Zombies—" … concerns fate, free will, time-travel, a forced sex-change operation and a serial-killer manhunt. It’s impressively insane and a lot of fun. “It’s absolutely out of its mind,” says Hawke, who plays a “temporal agent” flitting through time. “I love science-fiction that’s not oriented around action or effects. Whether it’s Robert Heinlein, Kurt Vonnegut, Philip K. Dick, H. G. Wells or whoever... that kind of mind-bendy science-fiction where you can really attack themes in a new way. And when I read Predestination it was like: ‘What the fuck did I just read?!’” He particularly likes the fact that although the lead character is transgender, the film is not explicitly about transgender issues, it’s about all of us. “There’s something about Predestination that actually does get at identity, for me,” he says."
