They probably interviewed Kevin James because Paul Blart was filmed in the Burlington Mall. As for Sandler, (being from NH)I would assume he's a c's fan even though he's a washed up, greedy, merger a deal with disney, sell out. I love Kevin James though, he rules even if Blart looks bad. I might see it just because of where it was filmed.
As for Marky Mark. I can't stand him, but why are we all the sudden calling him a lakers fan. I don't recall any of these guys sporting lakers gear, and if they did, they're just bigger sell outs.
