Ethan Hawke is set to reteam with his Daybreakers directors The Spierig Brothers, time-travel actioner Predestination. Based on the 1959 Robert Heinlein short story “All You Zombies,” this one concerns a covert temporal manipulation agency that’s tasked with jumping into the past to prevent/facilitate certain key events. Hawke will play an agent who must take highly inventive action to ensure his very existence. The original Heinlein story is a witty, mind-bending temporal-paradox that plays heavily with perspective. It’s unclear at this point exactly how closely the film will follow it; hopefully, the answer is: to the letter. Because, without spoiling anything, this one’s got a doozy of a last-act reveal. Hit the jump for more.
