julia roberts in dennis lee's fireflies in the garden

I recently heard about Korean American director Dennis Lee's Fireflies in the Garden, a small, quiet family drama boasting one really big star: Korean-American Snares Julia Roberts for Debut Film. Ms. Erin Brockovich herself. The Oscar-winning star agreed to be in the film after being deeply moved by Lee's screenplay, a fictionalized account of his own life. Not bad, for his first feature film. The cast also includes Willem Dafoe, Carrie-Anne Moss, Ryan Reynolds, Emily Watson, Hayden Panettiere and Ioan Gruffudd. Lee previously won the silver medal at the Student Academy Awards in 2003 for his student film Jesus H. Christ. My only question is, if this is a semi-autobiographical film based on Dennis Lee's life, which character is based on him? And can we expect to see any Asians in the movie?
