I haven't seen Wal-Mart: The High Cost of Low Price – mostly due to laziness, but also because I'm not sure if they're showing it in my neck of the woods or not. Of course, I could just buy the DVD, but again, laziness. As you probably already know, Robert Greenwald's (Outfoxed) film is not being shown in theaters, but rather community centers and other social gathering places. Greenwald's reasoning is that in order to spur change you have to get the movie in the hands of the people. In an interview with AlterNet he said, "What are the chances you're going to get someone to go to a movie on a subject they don't care about, or they disagree with you on? Very, very slim."
Is that really true, though? The Passion of the Christ used a similar grassroots approach, and while the majority of the people who saw it were probably Christian, it also attracted non-religious types like myself who thought it might just be a good movie. I'm not making a direct comparison between the two movies, but I think that if your movie is well-made you can attract just about anyone, even those who disagree with your assessment. I don't knock Greenwald's distribution approach, but I would argue that any movie stands a chance through old-fashioned theatrical distribution as long as it finds a way to engage the audience.
