Tales from the (Movie) Theater: Projecting (Part 3)

I was taught on what is known as a Two Reel System — the older carbon arc variety. No splicing of film together to make it one large, easy to project unit. Nope…didn’t happen. The Warner’s projection booth had three, count them three, Simplex carbon arc projectors. Museum pieces, really. Only two were used at any time. The third kept as cold backup for when one of others totally arrested on you, which could happen given the age of these antiques.
