Audi’s newest car commercial pits old Spock vs new Spock, as actors Leonard Nimoy and Zachary Quinto race each other to the country club to see who’s paying for lunch. (See? Celebrities are just like us!) On the surface, it’s a cute ploy that plays off next week’s release of the highly-anticipated CGI-delivery-system “Star Trek: Into Darkness.” But it also has a few obscure references for the more hardcore Audi-buying geeks (like Nimoy singing “The Ballad of Bilbo Baggins” which is either the lowest or highest point of the actor’s career).

That got us thinking. What are some other memorable science fiction commercials?

What do you get when you fuse two Cheerios together like horribly malformed Siamese twins? A new force at breakfast!

Let GE’s boombox of the future set you free from your humanoid overlords.

Before commercials were ironically epic, they were just plain epic. While this spot isn’t tied to a specific film, it’s one part “Brazil,” one part “Blade Runner,” one part Apple’s 1984 ad.

That’s the vision of the future put forth by 1993’s Sylvester Stallone film, “Demolition Man.” The only thing they get wrong? The “Demo Deal” made up of a Burrito Supreme, nachos, and a drink needs about four more items to reach the gastronomic heights a modern-day Taco Bell meal deal.

The T-Bell action starts at 1:01.

Levi’s Transformers Aliens Tarzan what?

See, the transformer represents our longing to change who we are, a change only fully realized by putting on a pair of Levi’s jeans. At least that’s what Don Draper would say.

And finally, The movie that launched a thousand ad campaigns

With Reese’s Pieces, “ET: The Extraterrestrial” turned product placement into an artform. But candy isn’t the only thing ET shilled in his brief time on our planet. He sold Ataris, Happy Meals, cereal, Speak and Spells, credit cards, and vitamins, to name a few. In this spot, ET comes back to Earth so he can drink all of his family’s Pepsi then feel ashamed by his insensitive behavior:
