"The Mummy's Hand"s production continued into mid-June, which led director Christy Cabanne and his crew to film into overtime hours. According to Peggy Moran, she had to be on set at 6am to do hair and makeup and filming began at 8am and would occasionally work as late as 4am the next day. Moran commented that "they could do that with people like me because we were under contract. The law requires that outside talent only work for X-number of hours, but me they could work all the time!" When asked about her fellow cast, she spoke positively about Dick Foran ("very nice and friendly") and Wallace Ford ("very funny always"). On Tom Tyler who played Kharis, she never met him without his make-up on, stating that he had to be at the studio at four in the morning and he couldn't talk with his make-up on.
