If you've seen Pixar's Inside Out, you're familiar with the five main emotions that are used to carry the story: Joy, Sadness, Anger, Fear and Disgust.
Today, however, director Pete Docter told USA Today that the list of possible emotions ran up to 26 at one point, with 14 serious contenders before it was eventually cut down to the aforementioned five.
Some of the emotions that didn't quite make it into the film, but that were worthy enough to get early sketches, include pride, greed, shame and embarrassment.
According to Docter, when they were doing first rounds of early research, they reached out to the scientific community to get an idea of just how many emotions humans actually experienced. The number fluctuated based the on different groups they spoke to, and at the end of the day, Docter said he had to make a decision based on how many complex emotions a young girl (main character Riley) would experience and what would translate best to an audience.
"I just remember sitting at my desk and saying, 'Okay, I'm going to have to make a call. Which ones feel instinctively like the ones appropriate for the story of this girl," Docter told the website. "And that's how we came up with the five that we have."
Docter also revealed that originally, the emotions had actual names instead of just being called the emotion they were. Anger was Ira, for example, while Fear was originally called Freddy until Docter decided to make it more simplistic.
Inside Out, which starred Amy Poehler, Bill Hader, Mindy Kaling, Lewis Black and Phyllis Smith was released this past summer and followed a young girl's move from Minnesota to San Francisco and told her story through the various emotions living inside her head.
The movie is available to buy on DVD and Blu Ray Nov. 3.
