In ‘The Mandela Effect,’ a man becomes obsessed with facts and events that have been collectively misremembered by thousands of people.

Believing the phenomena to be the symptom of something larger, the character’s obsession eventually leads him to question reality itself.

In this interview, writer-director David Guy Levy discusses why he’s obsessed with big ideas in film, what it means to make a smart horror movie like ‘Would You Rather,’ and how to make an audience use their imagination to fill in holes of a story.

Levy also discusses intriguing hooks in storytelling, when to cut aspects you love, how he puts himself into the story, how to show thinking on film, and why movies are more about questions than answers.
