1/13/2011 - With moving images now as close at hand as the nearest cellphone or iPad, it seems especially important to consider where they come from and how they may be transforming our reality. It's hard to think of a better place to address such questions than the Museum of the Moving Image, the only institution in the U.S. devoted to all forms of screen culture: film, television and digital media. It occupies a site cherished by cinéastes, the former Astoria Studio, which was once populated by glittering stars. Now an ambitious $67 million redesign and expansion, opening to the public Saturday, aims to rekindle some of that long-lost glamour while ushering the museum into the future.
