The first two days of filming on The Terror took place on the weekend after The Raven finished on a Friday. Corman directed all these sequences using the crew from The Raven. According to one report "mostly Corman shot people walking down hallways, entering doors and having a few conversations." The director says they had a rough storyline "but no one really knew what their character's motivations were because we didn't know what was supposed to happen to them." The uniform worn by Jack Nicholson was used by Marlon Brando in Désirée (1954). Boris Karloff later recalled: Corman had the sketchiest outline of a story. I read it and begged him not to do it. He said "That's alright Boris, I know what I'm going to do. I want you for two days on this." I was in every shot, of course. Sometimes I was just walking through and then I would change my jacket and walk back. He nearly killed me on the last day. He had me in a tank of cold water for about two hours. After he got me in the can he suspended operations and went off and directed two or three operations to get the money, I suppose... [The sets] were so magnificent... As they were being pulled down around our ears, Roger was dashing around with me and a camera, two steps ahead of the wreckers. It was very funny. Corman says they were so pressed for time towards the end of the second day, the crew shot footage without slating the shots. Dick Miller later recalled, "When we were shooting in the castle, none of it made any sense. Some of the things I did were ridiculous because I was a butler and I was there just for Karloff to talk to, for Jack to talk to, just a butler." The Raven had been financed by American International Pictures (AIP), but The Terror was financed by Corman privately, albeit using sets that AIP had paid for without asking for their permission. Samuel Z. Arkoff of AIP later said he became suspicious when he attended the wrap party for The Raven and noticed that the sets had not been taken down. He says he later discovered Corman was using AIP sets for the director's own movie but Arkoff knew Corman would "put that film in a vault, finish, and come to us [AIP]
