Here is the link to the new Making of featurette from Dreamgirls:
"Apple.com's Quicktime and iTunes will launch a brand new behind-the-scenes video featurette on May 22 for the upcoming movie musical 'Dreamgirls.'"
Head on over to moviemusicals.net, Andrew has put up some screen shots from the featurette. I posted a couple at the bottom. I am working on getting the video capped and getting more screen shots. Check Back!
