In 2014, Lee cast Sol Kyung-gu and Park Hae-il in his third film, My Dictator. Set in the 1970s, the film is about a bit part theater actor (played by Sol) whom the Korean Central Intelligence Agency hires as the body double for Kim Il-sung in the rehearsals for a historic North-South summit between Kim and Park Chung-hee. Lee spoke candidly, "I thought I could tell a story about an actor, and at the same time, about one individual who lived in tumultuous times. Moreover I felt like I could tell a story about the lives of fathers who went through those times. I once saw a photograph of my Father a long time ago. He was so young. But I was curious what made my Father, who had been so young, into the dictator-like Father that he was now. Thinking about it, it seemed that having passed through an era rife with dictators in both the North and the South, he couldn't just stay young. [...] Like all the fathers of our time, he is awkward at communicating affectionately with his offspring. I think that hurt me a little bit, too. [...] In that way, my Father was someone who made me follow his own stride. Now that Father of mine has fallen into a condition where he is ill and cannot even speak properly, I want to broach and speak of the things that made me most uncomfortable with him. The greatest way I can do that is through a film. So in a sense, My Dictator is a film in which I have put my heart's Desire to reconcile with my Father."
