Balint was co-founder of New York's Squat Theatre where he wrote, acted, and directed L-Train to Eldorado and Full Moon Killer.
[2] The group grew into a collective that became well-known to younger artists throughout Budapest for trying to invent a new type of avant-garde production.
In 1976, Balint, along with a number of other artists in the collective, toured theater festivals throughout Europe with the troupe, before relocating to New York City in mid-1977, where he changed his name to Stephan.
[3] He also acted in several films, including Hunter, directed by Robert Frank, written by himself; American Stories: Food, Family and Philosophy in 1989; and The Golden Boat in 1990.
[2] Balint returned to Budapest in the early 1990s, continuing his work until the start of his long illness in 2002, dying in 2007 of pneumonia.
