So the market said yes to Time Warner's (NYSE: TWX) new movie starring Jim Carrey, Yes Man. I know, that's an awful pun, and I'd be willing to bet that other articles about this past weekend's box office results said something similar. Sometimes you just can't resist. But, yes, Yes Man ruled at domestic multiplexes and grossed about $18 million according to early estimates from Boxofficemojo.

Here's the thing, though -- is an $18 million opening that great for Jim Carrey? Furthermore, as of the early estimates, Sony's (NYSE: SNE) Seven Pounds, the number-two film, actually grossed only $2 million less than Yes Man, and to add further insult, its per-theater average was higher. Shouldn't Carrey's star power have guaranteed a wider margin of victory? For that matter, what's Will Smith, the star of Pounds, doing in second place?

It just goes to show institutional shareholders of media companies that big star salaries simply do not guarantee runaway hits on the silver screen (I keep hoping that they'll complain about celebrity compensation, but so far, there have been no takers whatsoever).
