Alex Garland may have introduced himself as a director with Annihilation, but it was 2014's Ex Machina that helped to cement him as a great sci-fi writer/director. Starring Alicia Vikander, Oscar Isaac, Domhnall Gleeson, and Sonoya Mizuno, the film follows Caleb, a young developer who is sent to his boss' idyllic villa to perform a Turing Test on his newest creation, a humanoid android named Ava. The film is as profound as it is mind-melting, which has led many fans to come up with their own theories online. Unfortunately, the most popular theory circulating among fans has just been denied by the director.

Alex Garland recently sat down with GQ to look back on his past movies, while promoting his new film Warfare. Whilst on the topic of Ex Machina, where the director explained the idea behind the film and his personal casting process, Garland was also asked to clarify a popular fan theory.
