*edit* To be clear, I am going to be an undergraduate, but I just went through a very similar decision. I turned down production at Chapman to do Critical Studies and Business at USC on the basis that I would do Production in grad school.
I am going to be doing Critical Studies at USC next year, and I am also most likely going to double major with a Business degree. From what I've gathered (talking to graduates, admissions representatives, and others at both Chapman University and USC), Cinema Studies alone would still be a fine undergraduate major for entry into a graduate film program; add in a business degree, and that only increases your diversity. My questions were, however, geared towards doing Production during grad school, so the situation might be different for the PS program. Indeed, business and CS might be a bit redundant, but I'm in no way sure.
Have you also taken into account that USC has a business degree with a cinema focus. It's basically a major and a minor, and I would think would be similar to the Stark program.
