Sid Haig admitted to avoiding Lon Chaney Jr. for the first two days of filming, simply because he wasn't sure what to say to the veteran actor. One day Chaney was needed for and Haig was sent to Chaney's trailer to retrieve him. Haig nervously knocked on the door and said, "Excuse me, Mr. Chaney. You're needed on set." Chaney told Haig, without skipping a beat, "Stop that. I'm not Mr. Chaney. I'm Lon. You're Sid. Let's leave it at that." Haig later said that this interaction put him completely at ease.

The studio where the bulk of the film was shot (in August of 1964) was not equipped with air conditioning, only fans. With temperatures in the triple digits outside, the crew were all uncomfortable, but none more than Lon Chaney Jr., who was often dripping with sweat by the end of his takes. A bucket of ice water was brought in so Chaney could be mopped down with a cold, wet towel after each take.
