Lo was first noticed for her stylistic 35mm feature film Black & White: A Love Story which she wrote, directed and produced at the age of twenty-six. The film was accepted into the American Independents at The Berlin Film Festival and went on to win a best directing and best feature film award in Montreal. At the 1996 Berlinale, Joe Leydon of Variety describes Susanna Lo as an intelligent writer who scrupulously avoids predictable melodrama.
