Heckel's latest film, Unspeakable, is her first feature. Twenty years in the making, it's a non-fiction narrative exploring her father's suicide and the deeper truths revealed about the American family. It recently screened at DOX BOX 09 in Damascus, Syria, and won a Grand Jury Award - The American Falls Award for Best Western New York Film - at the Buffalo Niagara Film Festival. Heckel wrote, produced, directed, shot, and edited Unspeakable, creating a film form that unfolds her experience of her father's suicide in a way that makes her personal story a universal experience of family. She combines silent scenes with actors, self-portraits, home movies, evocative landscapes, photos, narration and voice-over interviews. Images and sound work as counterpoints to one another, creating an inner experience of memory and discovery.
