Ben Byer is a Chicago writer, filmmaker, and actor who's appeared on the stages of Steppenwolf, Trap Door, Organic Theater, and others. Six years ago at the age of 31 he was diagnosed with ALS, a neuro-degenerative condition more commonly known as Lou Gehrig's disease. As the disease began to rob Ben of his speech and motor skills, he decided to head out and find out more about ALS and the people it affects. Indestructible documents Ben's journey, a trip that takes him around the world and into his own psyche. We recently spoke with Rebeccah Rush, Ben's sister and the film's co-producer. She says she had to open her mind, heart – and home – to get the documentary off the ground.
