We're All Going to the World's Fair is a 2021 American coming-of-age psychological horror film[7] written, directed, and edited by Jane Schoenbrun.

[9] The film follows Casey (Cobb), a teenage girl who takes the "World's Fair Challenge" and documents the mental and physical changes that it causes her.

Casey, a lonely teenage girl living with her single father, records herself taking the viral "World's Fair Challenge".

In a video, Casey recounts bouts of sleepwalking she experienced when she was younger and says she has begun feeling similarly since taking the challenge.

JLB is revealed to be an equally lonely middle-aged man who spends his time watching many people's World's Fair videos.

In her next video, she covers her face and arms in UV reactive paint and tears apart the stuffed animal she has slept with since she was a newborn.

A number of performers appear in various real and staged YouTube videos, including Theo Anthony, Valeria Santiago, May "NyxFears" Leitz, N8 Detroit, Trevor Lahey and the ASMR content creator Slight Sounds.

[14] Schoenbrun wanted to explore dysphoria in relation to the internet in how something in the online space can exist independent of physical form or constraints.

The critics consensus reads: "Narratively challenging and visually haunting, We're All Going to the World's Fair adds a uniquely ambitious and unsettling entry to the crowded coming-of-age genre.
