Donor Unknown is a 2010 documentary film directed by Jerry Rothwell and produced by Al Morrow and Hilary Durman.

She grew up in Lander, Pennsylvania in rural Warren County[1] with two mothers, and a burning curiosity to know more about her anonymous donor father.

The article also falls into the hands of Jeffrey Harrison, living alone with four dogs and a pigeon in a broken-down RV in a Venice Beach car park.

Funny, moving and surprising Donor Unknown raises intriguing questions about our understanding of parenthood, and the strange power of the genetic imperative.

Peter Bradshaw of The Guardian called it a 'amusing and sweet-natured documentary' although he felt that there might be a deeper, more complex story to tell about the siblings' relations with each other and Harrison's own life.
