Hayley Mills Reveals the Rock Music Icons She and Her “Parent Trap” Double Susan Henning Dated After the Film’s Success

Hayley Mills, renowned for her dual role as Susan Evers and Sharon McKendrick in the iconic 1961 Disney film “The Parent Trap,” celebrated her 80th birthday recently and took a moment to reflect on her unique filmmaking experience. In a podcast interview, Mills recounted the behind-the-scenes challenges of portraying twins long before the advent of advanced computer technology.

The magic of the film was largely achieved through a technique known as split screen. Mills explained that the process involved filming each side of the scene separately. “The camera was in a great big box, and they would film one side of the screen at a time,” she stated. With meticulous planning, Mills would perform her scenes while interacting with her photographic double, Susan Henning. Henning, who took on the task of mimicking Mills from behind, was pivotal in creating the illusion of two distinct characters.

Creating such scenes, however, was no simple feat. Mills elaborated on the rigorous techniques that were employed to ensure continuity. “You had to be very, very careful. For example, there was a scene where we were both sitting on a bed together, and you had to get out of the bed so slowly because if you moved the sheet, there was a split line,” she explained, illustrating the precision required for the shot to be seamless.

Mills expressed deep appreciation for Henning’s contribution to the film, noting that her co-star’s efforts were vital in maintaining the film’s visual integrity. “She would wear her wig, and you’d see her neck, which was actually longer than mine. Whenever we walked away together, she cleverly positioned herself so you wouldn’t see our faces, creating a believable effect,” Mills said.

While Mills’ portrayal of the twins garnered her fame, she acknowledged the more thankless role Henning played. “Poor girl… It was pretty thankless because she was always just seen from behind,” Mills remarked. She empathised with Henning’s situation, recognising that only the back of her head was on display throughout most of their collaborative scenes.

Despite the challenges involved, Mills noted that the two women enjoyed their time on set together. She humorously recalled how Henning had to have a cast made of Mills’ nose, leading to some funny moments during filming. “If they got a glimpse of her nose because she turned a bit too much, they’d see my nose instead,” Mills chuckled.

Following the release of “The Parent Trap,” Henning went on to achieve great success as a dancer and even encountered a bit of Hollywood romance, participating in a show with the legendary Elvis Presley. Mills light-heartedly remarked, “I think she scored there,” reflecting on the fortuitous turns Henning’s career took after their film together.

The interview also revealed Mills’ own dash of romance during that era. She fondly recalled a date she had with George Harrison of The Beatles, offering an amusing anecdote from their evening together. “As soon as we sat down, we were surrounded by people clamouring for autographs,” Mills shared. Despite the chaos, she described Harrison’s composure during the experience, noting that one fan even knelt in her lap just to reach him.

Their plans to enjoy a screening of “Charade,” featuring Cary Grant and Audrey Hepburn, were thwarted by the crowd’s eagerness. Mills detailed their attempt to leave the event as fans chased after them. “George jumped into the car, and some fool slammed the door shut, leaving me stuck outside,” she recounted, vividly illustrating the wild nature of celebrity life during the height of The Beatles’ fame.

Mills continues to reflect fondly on her career and the friendships formed during her early years in the film industry, including the enduring connection with her fellow actress, Henning. As she celebrates her milestone birthday, her recollections reveal not only the challenges of filmmaking but also the joy and camaraderie that can blossom amid the pressures of showbusiness. “The Parent Trap” remains a cherished classic, partly due to the enduring talent of both actresses and the innovative techniques that brought the story to life.
