The Secret Friend is a 2010 comedy-drama film based on the 1997 short story of the same name by Brazilian writer João Silvério Trevisan. The film, directed by Flavio Alves, features Viola Harris and Siobhan Fallon in the major roles. The film differs substantially from the original short story, which initially created some tension between the writer and the director. Filming took place in early 2009, mainly in Brooklyn, New York, and debuted at the 2010 Palm Springs International Film Festival, where it was chosen as Best of the Fest. The film centers around the character and life of Anna Marshall, a lonely, elderly widow living in a suburb of New York City, who develops a mysterious friendship with a silent caller. Although a screenplay for a feature version of the short film was written, as of 2011, it has not been officially greenlit.
