While many weren't too familiar with ALS (a.k.a. Lou Gehrig's Disease) before this summer, the hundreds of Ice Bucket Challenge videos helped spread awareness of this degenerative disease. Today, we have the first trailer for You're Not You, which stars Hilary Swank as Kate, a pianist who becomes stricken with ALS.Based on Michelle Wildgen's book, this drama follows Kate and her husband (Josh Duhamel) as they find the most unorthodox caretaker in young college student Bec (Emmy Rossum) as they both change each other's lives.
