Starting out in the field of practical special effects and models, Johnson was one of the first people outside of Industrial Light and Magic to see Star Wars (albeit in an incomplete form) as chronicled in his semi-autobiographical film 5-25-77.

[1] He had also visited the set of Close Encounters of the Third Kind at Future General Corporation a few days before and found Douglas Trumbull's work to be "engineered, intimidating and mature" compared to John Dykstra's "shooting-from-the-hip" style.

Johnson ascended into mainstream Hollywood filmmaking following the modest success of Spaced Invaders, invited by John Hughes to work on his adaptation of Dennis the Menace, and then later, the comedy Baby's Day Out.

[7] On May 25, 2012, the 35th anniversary of the release of Star Wars, Johnson began a cross-country road trip in his 1975 Ford Pinto to attract the funding needed to finish the film's remaining post-production work.

[8] Johnson spent the summer of 2012 test-screening 5-25-77, his trip also becoming the subject of a documentary called Hearts of Dorkness, by filmmaker Morgan Flores.
