I devoured each of what Halliday referred to as “The Holy Trilogies”: Star Wars (original and prequel trilogies, in that order), Lord of the Rings, The Matrix, Mad Max, Back to the Future, and Indiana Jones. (Halliday once said that he preferred to pretend the other Indiana Jones films, from Kingdom of the Crystal Skull onward, didn’t exist. I tended to agree.)
I also absorbed the complete filmographies of each of his favorite directors. Cameron, Gilliam, Jackson, Fincher, Kubrick, Lucas, Spielberg, Del Toro, Tarantino. And, of course, Kevin Smith.
I spent three months studying every John Hughes teen movie and memorizing all the key lines of dialogue.
