Star Wars and Indiana Jones are the two most popular film franchises created by George Lucas, and a startling theory explains how their stories could be connected. Exhausted from Star Wars’ troubled production and worried the movie would be a flop, Lucas went on vacation to Hawaii with his friend and fellow filmmaker Steven Spielberg instead of attending the premiere. While there, Lucas pitched his idea for what would eventually become Indiana Jones, and the first movie, Raiders of the Lost Ark, was released four years later in 1981.
