Since he was a child, Jun always had an interest in film and literature; inspired by the work of Sam Shepard, Neil Simon and Samuel Beckett.
Jun's first work was the short film For Jimmy Brown, a hospital drama dealing with racial issues.
This marked the end of two years of searching for a production company as the Los Angeles firm agreed to produce the film.
The film was generally received well by critics: reviews from both The New York Times and Entertainment Weekly praised the strength in depth of the supporting characters.
Entertainment Weekly summarised that "Steel City could have used more rhythmic drive, but if Jun keeps weaving together characters this compelling, he could be a major film artist in the making".
