A lot of work went into turning Lily James into Pamela Anderson.
In an interview with Entertainment Weekly, James explained that she spent hours every day getting ready for her close up. "I was in the makeup chair at 3:30 a.m., and there would be this four-hour process to get me into the Pamela look," she said. "Eyes, wig, teeth, there was just a whole process."
Aside from hair and makeup, James also said that she had a personal trainer and watched a lot of interviews of Anderson to perfect her voice.
