The film's website says that it'll make its TV debut on HBO during Black History Month next year (2012) on Valentine's Day. 

Before that, however, if you'll be attending the Palm Springs International Film Festival later this month, you'll get to see it on the big screen, because it's screening in the festivals World Interests documentary section.

Directed by Nancy Buirski, The Loving Story as the documentary is called, centers on a real-life story of Richard and Mildred Loving, an interracial couple living in the state of Virginia where interracial coupling was illegal, and their struggles, including the US Supreme Court case named after them – Loving vs Virginia (1967), the landmark civil rights case in which the United States Supreme Court, in a unanimous decision, declared Virginia's anti-miscegenation statute, unconstitutional, overturning existing laws and bringing an official end to all race-based restrictions on marriage in the United States.  

Persecuted by a local sheriff, the Lovings (he was white, she was part black and part Cherokee) were found guilty of violating Virginia's law against interracial marriage and forced to leave the state. But Mildred Loving chose to fight. She wrote a letter to Attorney General Robert F. Kennedy asking for help .He referred her to the ACLU and two young attorneys took the case. Drawing on extensive archival footage, and on contemporary interviews with the family and the attorneys, the film vividly brings a monumental court case to life.

The film was shortlisted for the Best Documentary Feature Oscar.

As already noted, the HBO co-production, which has been touring the film festival circuit over the last year, will debut on HBO in February 2012. Those in the Palm Springs area and vicinity can see it before then at the PIFF, when it screens on the 8th and 9th of January 2012.
