Query: A must Have

The movie was great and the special feature disk tells you and shows you almost any and everything that you want to know about the making of the film, the background of the artist and how Dream Girls just came to life. Also, you get to see all of the hardwork that the actors put into their role which looks so effortless on screen. The DVD with the bonus feature is well worth the few extra dollars.
