Avatar director James Cameron took a shot at President Donald Trump in an interview with the Hollywood Reporter published Wednesday, arguing his Avatar films are on “the right side of history.”

Cameron spoke about rising concerns about artificial intelligence and the environment in his new interview, as well as the impact his movies have had on them. While addressing this impact, he described the president as the “most narcissistic a**hole in history since f***ing Nero,” telling the interviewer he could be quoted on this.
