Truong directed her first feature film in 2012 previously titled nightdreamblues but was re-titled Someone I Used to Know, written by West Liang, and starring Brian Yang, Eddie Mui, Emily Chang, West Liang, Tzi Ma and Diana Lee Inosanto. The film was premiered at the 2013 CAAMFest, formerly known as the San Francisco International Asian American Film Festival, and was described as "a bittersweet drama" that is "a new-millennium remix of such classic eighties' ensemble dramas as The Breakfast Club and St. Elmo's Fire." It was also screened at the 2013 Los Angeles Asian Pacific Film Festival and the 2013 Asian American International Film Festival in New York City, drawing further comparisons to the films Less than Zero, The Anniversary Party and Who's Afraid of Virginia Woolf?.
