‘Elemental’ Director Peter Sohn on How the Periodic Table and His Parents’ Immigration Story Inspired Pixar’s Latest Feature

The story behind Pixars latest animated feature Elemental is a personal one to filmmaker Peter Sohn. The opening shows a family arriving at the fictional port of Elemental City, which closely reflected the immigration story of Sohns parents from Korea to New York.

The story breathes life into the earth elements of fire, water, land and air, depicting them as residents of Elemental City. When Ember (Leah Lewis), a fiery young woman, meets go-with-the-flow water being Wade (Mamoudou Athie), they discover that, despite their conflicts, they have a lot in common. As the two fall in love, Ember is faced with the internal conflict of being with Wade or following in her parents footsteps and running the family business. As the son of first-generation immigrants, Embers struggle reflected not only Sohns personal experience, but that of many of the animators and storytellers behind the scenes.

Below, Sohn talks with Variety about why Elemental was seven years in the making, and what it means to immortalize his story in animation history.

Elemental had its premiere the other night. How did that feel?

It was very emotional. There was a huge sense of pride. Ive never done anything as personal as this before. So, this was a new experience for me in terms of sharing a part of myself with audiences. Its scary, but its not just my story. Its the co-workers and crew. They gave their stories, and that movie was inspired by many other people.

In early development, I lost my dad, and at the end, I lost my mom. So, theres been an emotional attachment to just finishing it and tying it to closure.

The world of Elemental is vibrant and colorful, how did you work with the animators to build the city?

This was seven years in the making. There was no pathway for the characters. The studio, in the past, has made characters that are plastic or metal cars or humans with asubsurface scattering in the skin, but there was no path to create a character that was wholly an effect and it was scary because everyone had a naysayer about it, or if they could render it. So, the journey to get this character, Ember, to blink was difficult.

The first time we showed Embers face, and she blinked and did a little smile, was such a milestone and so meaningful. To create something that was a gas that you could connect to was hard. Her first designs were really terrifying because she looked like a Weta FX character from Lord of the Rings.

What were the design challenges that came with injecting soul into fire and water elements?

I was drawing these fire characters as superheroes. They were throwing their elements out of them. I drew these two hands, water and fire coming together. They didnt touch but the temperature from her hand would heat the water to boiling point, and there would be a cooling down effect. It felt like goosebumps when you were about to touch someone for the first time. Or when shes angry, she explodes into this fire and changes shape. She can get mad without saying anything.

We were making this connection to different feelings that you would have in a relationship with someone, and that was our big game that audiences can connect to.

The opening of the film really celebrates immigration what does that mean to you to be able to celebrate your parents journey, and immortalize it forever?

I hadnt thought about it that way. I was a very naive and jerk kid to my parents, because growing up in that world I didnt realize how hard it is. When my parents were telling me their stories of having survived the Korean War or they had nothing, I would say, OK, can I play video games now? I was that type of kid. The older I got, it started to sink in. How did they do this without knowing the language? When I got married and had kids, it started to dig into me about how much I appreciated what they had given. So, that opening was to show how hard it was for them, as outsiders coming into this new world.

Since the characters are based on the elements, are you a big science lover?

I like science, but I wasnt that great [at it]. I think thats why I loved animation so much, because it was like this magical little thing that could happen when you flip pages. With the periodic table and breaking down the atomic number and how that was tied to the elements, it was different for me. This idea came from drawing buildings on top of this periodic table and making them into characters.

What is themessage that you want people to take away from Elemental, whether they experience it in theaters or at home on Disney+?

It is a very sincere film. I never thought I would be connected to something so personal. Its about thanking our parents. I got lost in making this and every time I did, Id go back to the north star of appreciation for them, and it wasnt easy making that sacrifice. Its also aboutbridging that gap between someone from a different culture, and that empathy.
