Friends With Benefits starred Justin Timberlake and Mila Kunis. Little did the fans know, Kunis was actually living the film in real-life alongside her future husband Ashton Kutcher.

Nonetheless, the film was a success and Kunis was praised for her chemistry alongside Justin Timberlake. However, as we'll reveal in the following, things weren't always the smoothest behind the scenes. In fact, at the start, Kunis wasn't into the script and knew that it needed a lot of work to improve.

We'll take a look at the script change along with the reason why Mila requested a backside double. In truth, she isn't the only actress to request a double for a comedy. Isla Fisher and Rebel Wilson are other stars that used a double, and their reasoning makes complete sense. Let's take a closer look at how it all went down.

Requesting a body double really isn't anything new, particularly for a revealing scene. Isla Fisher was praised for her performance in Wedding Crashers, however, the actress didn't feel the need to expose herself in the film.

She stated, "I feel like if you have a female comic character, and then you see her nipples, then she is no longer funny, which is clearly wrong, but that was my theory, and that’s why I didn’t want to do it.”

Fisher might have a point as that type of scene didn't make much sense for the plotline, and the direction her character was headed towards.

The same held true for Rebel Wilson who asked for a double during her time in Grimsby. Wilson had a clause in her contract from the start that she wouldn't work revealing scenes.

"They wanted full-frontal nudity. We write in the contract, specifically, 'No nudity'. They got in another girl — this larger burlesque dancer from South Africa — to be a nude double. And they got her to do all this stuff," Wilson told the publication.

Mila Kunis revealed that a separate audition was held to match her backside. Speaking alongside Ryan Seacrest, Kunis stated that the film was looking for the backside that resembled her own the most.

“These young ladies came in,” she explained. “They were in a casting room and I was there, the director and the casting director and my makeup artist were there. And these lovely women had to show us their derrieres and we chose the one that resembled my body the most without looking like it’s fake.”

Kunis reasoning for using the double made complete sense, as the actress didn't feel the need to over expose herself throughout the film.

“I showed side-boob, and I figured I can’t just give away everything all at once,” she joked. “I gotta let it all out in little pieces here and there.”

As for Justin Timberlake, he was okay with the revealing scenes. “I only did it because I’m young now, and everything’s where it’s supposed to be,” singer-turned-actor has said of of the nudity. “I figured this is the time, before gravity gets the best of me.”

Despite the minor hiccup in the film, it didn't lessen Mila Kunis' experience on set.

At first glance, Kunis wasn't into the script, feeling as though it was outdated. The actress revealed, "When I got the script it was very dated but I knew it made for a funny movie so I took a meeting with Will Gluck. Will, Justin and myself went out to dinner and that's when we realized we wanted the same thing for the movie."

Following the rewrites and the fact that the crew shared the same vision, Kunis had a blast shooting the film.

"We were able to workshop it, re-write the script and tailor the characters to what we feel our generation is like now. A lot of the time you go to work then you have lunch by yourself and then you go back to work. There are those few movies where you actually sit down with your co-star and your director and have lunch together."

The rom-com itself received decent reviews while turning a healthy profit. Off a budget of $35 million, the film made $149.5 million. Kunis and Timberlake's chemistry was a major part of it.
