Voltron is based on the Japanese sci-fi series Beast King GoLion and Kikou Kantai Dairugger XV. World Events edited and dubbed the series as a syndicated show, titling it Voltron: Defender of the Universe, that ran in the mid-1980s. The premise centered on five young pilots in a battalion named the Robot Lions, which are vehicles that join together to form a mega robot known as Voltron.
Hollywood has tried to launch a live-action Voltron movie since the early 2000s, to no avail. Mark Gordon and Pharrell Williams were part of a team that tried to mount a project in the mid-2000s, and later New Regency got involved. In the early 2010s, Relativity Media was developing a feature with Thomas Dean Donnelly and Joshua Oppenheimer. DreamWorks at one point tried to develop an animated feature.
