Filmmaker Magazine said, “the most emotionally devastating film at the Sundance Film Festival this year was a short.” The film won a Special Jury Mention at Aspen Shortsfest, Best Documentary Director’s Choice at Rincon, and was a Finalist at the Ashland Film Festival, and has been invited to screen at many notable festivals, including Sheffield Doc/Fest, LA Film Festival, and AFI Docs. The film has so far raised over $105,000 for Huntington’s Disease research. In development right now is a special page on the HDSA website where people can donate to HD research in Marianna’s name.
