All films at Fort Union Drive-In are shown on a vintage carbon arc projector system - the original equipment from the theatre's birth in 1948!
Carbon arc projectors work similar to an arc welder. A brilliant spark forms between a carbon rod and an electrode and the blazing glow — the equivalent of a 4,000-watt bulb — is focused by a powerful mirror into the projector’s lens.
Despite having upgraded the audio to stereo FM radio, there are still a few working Drive-in window speakers here for the nostalgically inclined.
