Earlier this week, conservative radio provocateur Rush Limbaugh asked his audience if it was "accidental" that the villain in 'The Dark Knight Rises' was named Bane, given that GOP presidential candidate Mitt Romney's ties to Bain Capital have been scrutinized by the Obama campaign.

Limbaugh's critics pounced all over that allegation, pointing out that Bane has been a Batman villain since 1993, and 'The Dark Knight Rises' was conceived well before any controversy surrounding Romney's role with Bain Capital.

Limbaugh then clarified his initially questioning, saying what he really meant was the
"liberal" media would tie Bane to Bain, not that he believed the movie itself was anti-Romney propaganda.

However, maybe Rush should have stuck to his first story. Conan O'Brien got his hands on a preview of 'The Dark Knight Rises' and it seems to confirm all of Limbaugh's initial concerns. Check it out.

In the clip, Bane growls that "the streets will run red with blood before I release my tax returns," among other anti-Romney digs.

So it looks like Christopher Nolan was on the Obama payroll all along. Actually, given the absurd amount of money that goes into presidential campaigns these days that's not as ridiculous as it sounds. Political ads in movies could well be the next product placement.
