"Iron Man 3," "Star Trek Into Darkness" among Super Bowl movie ads

Sunday night's Super Bowl resembled a trip to the movies, with several potential summer blockbusters airing new ads before and during the big game.

Three film trailers aired through the first half and halftime and several others were broadcast during the lengthy pre-game show.

While ad rates for the Super Bowl are notoriously expensive -- $4 million for 30 seconds during Super Bowl 47 -- they can generate buzz and potential ticket sales.

"The cost per minute is enormous, but studios obviously feel they are going to get the biggest bang for their buck," said Paul Dergarabedian, box office analyst for Hollywood.com.

Reactions to an ad for "Fast & Furious 6" quickly started trending on Twitter, with franchise star Ludacris fielding viewers' responses.

Also airing in the first half were promos for "Star Trek Into Darkness" and the "Oz The Great and Powerful." After lights went out in the Super Dome in the third quarter, an ad for "Iron Man 3" aired.

Film ads also played a prominent role in the ramp up to the game.

Walt Disney Co. co-sponsored an hour of pre-game coverage and used it to promote "The Lone Ranger," which stars Armie Hammer and Johnny Depp. In addition to a 90-second promo for the film, CBS aired a tie-in interspersing scenes from the film with footage of the 49ers and Ravens playing.

"World War Z" also aired an ad right before the game's kick-off.

"Identity Thief," a comedy starring Jason Bateman and Melissa McCarthy, was the rare film that will be in theaters before the summer movie season. Another February release, the Dwayne Johnson action film "The Snitch" aired an ad about 90 minutes before the game's start.

The vast Super Bowl audience makes it almost imperative for big releases to air ads during the game, Dergarabedian said, although several studios opted not to air any promos during the game.

"If you don't have a movie to crow about during the Super Bowl, then maybe your slate isn't strong enough," he said.
