When Falken pulls up a list a games for WOPR to play the display reads (in part):
- "#ABSOLUTE_TAKEOVER===001 #JOI_MINDTRICK===010"
- "#MAKE_ME_SWAY===100 #TAKIN_CARE_OF_BUSINESS===011"
- "#PILLOW_TALK===101 #GAME_THEORY===110"
- The binary number after each filename has the games out of order. If they are read by row then column they're listed in order of 1, 2, 4, 3, 5, 6. If read in column then row order it's 1, 4, 5, 2, 3, 6. Alphabetical order by filename doesn't work either.

An automated people-mover train is shown passing over the roof of the airport terminal as the students are boarding their plane at Philadelphia International Airport. PHL has no people-mover. Full-sized commuter trains operate between terminals on ground level.
