AWARD-WINNING actress Dame Helen Mirren has made an advert for Budweiser warning Americans about the dangers of drink-driving.

The 60-second ad telling drivers not to be “a pillock”

will be screened during Sunday’s Super Bowl, the showpiece American Football final.

In the advert, the 70-yearold former St Bernard’s High School pupil delivers a speech as a regal soundtrack plays in the background in a reminder of her Oscar-winning role in The Queen.

She tells viewers: “I’ll sum it up like this: If you drive drunk, you, simply put, are a short-sighted, utterly useless, oxygen-wasting, human form of pollution, a Darwin Award-deserving, selfish coward.

“If your brain was donated to science, science would return it. So stop it. The chances are you’re a fun, solid, respectable, human being. Don’t be a pillock!”

The word is not in common in the US, so reports have also included a description.

CNN, for example, said “pillock” is “an obscure English insult, meaning fool or stupid person”.

The Denver Broncos will play the Carolina Panthers on Super Bowl Sunday.
