Bubble, the first movie of Steven Soderbergh’s six picture deal with Mark Cuban’s HDNet, is a two-pronged experiment in both distribution and technique. On the business side, it’s the first film to have a deliberately orchestrated simultaneous release in theaters, on cable television and on DVD. Soderbergh and others believe that the DVD “window,” the period of time between a film’s theatrical release and its home video release, is inexorably shrinking to nothing. Others, especially some in the movie theater industry, think that this window is rather vital to their business model and that Soderbergh is full of it. This led more than a few theater chains to boycott this film because of its simultaneous DVD release.
