The main attraction during Sunday's Super Bowl will no doubt be the game between the Denver Broncos and the Seattle Seahawks, but what about the commercials?

At $4 million a pop, these 30-second spots will go all out in promoting some familiar brands. And according to earlier reports, expect lots of hashtagging.

You'll see Stephen Colbert promoting pistachios, Scarlett Johansson pitching SodaStream (an edited version of the ad will air because the original was banned by Fox for calling out Pepsi—one of the Super Bowl sponsors—out by name) and puppies will star in a Budweiser commercial soundtracked by Passenger's hit song "Let Her Go."

As we previously reported, music will be key. Outside of Bruno Mars and the Red Hot Chili Peppers' halftime show, U2 will also premiere new song "Invisible" in the form of an ad, while OneRepublic, Zedd and others will have music featured onscreen as well.

Take a look below at some of the ads before they air.
