Transformers, Captain America, Spider-Man return with new trailers

As we all know by now, the Super Bowl isn't just about a football game. And it's not just about splashy ads for products either.

Studios also use it to launch new trailers (or at least first looks at upcoming films). In some cases, the 30-second movie ad is just a teaser for the full trailer online.
In the case of "Transformers: Age of Extinction," the ad was all we got but it was the first anyone had seen of Michael Bay's big fourquel, with new human star Mark Wahlberg.
The spot doesn't just feature the former Marky Mark running from the evil Decepticons' reign of terror, it also includes the already-much discussed sight of Optimus Prime riding a Dinobot.
