If you think that the ability to see is the first requirement for being able to make a movie, then you haven’t been to Kevin Bright’s film-making class at the Perkins School for the Blind in Boston. Rock Center's Harry Smith visited Bright, one of the executive producers of the wildly successful show “Friends,” taught his students how to make films – even though many of them are completely blind. The videos they made show that while the students don’t have sight, they do have vision, and they provide a rare window into the world of the blind. Watch Smith's full report, Fri., May 24 at 10pm/9c on NBC's Rock Center with Brian WilliamsMay 23, 2013
