Helen Mirren slams drunk drivers in a stellar Super Bowl commercial.

Every year, advertisers bring out the biggest and brightest to star in their Superbowl commercials. At $5 million a pop, you’d want your ads to have some serious star power.

And there is no star more powerful, articulate or elegant than Dame Helen Mirren.

While one might expect her to be more of a Chateauneuf du Pape gal than a Budweiser fan, the ad is for a noble cause.

The prevention of drunk driving.

Mirren tells would-be law-breakers that “simply put,” they “are a short-sighted, utterly useless, oxygen-wasting human form of pollution.”

And if that isn’t enough to shame you out of it, Mirren thinks you are “a Darwin award-deserving selfish coward.”

“If your brain was donated to science,” she quips, “science would return it.”

Her eloquent and cutting insults are finished with two words, that seem to hold so much more power when uttered by a woman with as much gravitas and presence as one who played the actual Queen (twice):

“Stop it.”
