After he received his diagnosis of multiple sclerosis, the filmmaker Jason DaSilva began working with his creative partner Alice Cook on the feature documentary “When I Walk,” which is having its premiere at the 2013 Sundance Film Festival.

His past documentaries have been shown on PBS/POV, HBO and at the Sundance Film Festival.
