Getting its World Premiere at the 2026 Sundance Film Festival, begins in the 1950s, recounting the unbelievable story of Joybubbles, (the legal name of the former Joe Engressia since 1991) as he discovers he can control the global telephone system simply by whistling a magic tone. Born blind and hungry for connection, his early obsession with the telephone sparks a subculture that shapes the future of hacking and modern technology in the 20th century. Told through vivid archival footage and Joybubbles’ own voice recordings, the film celebrates a visionary who redefined connection and challenged assumptions about disability, identity, and imagination. JOYBUBBLES pulses with the curiosity and wonder he brought to the world, brought to life by our guest, director Rachael J. Morrison’s inventive, tactile storytelling.
