The first trailer for "Eclipse" was pretty ho-hum unless you know the story well, but subsequent reveals have mostly been focused on the action. It's a good thing too, as that action is what Summit is hoping will bring in the all-important male audience. We dudes couldn't care less about a vampire-werewolf-human love triangle, but bloodsuckers fighting dog people is another story entirely.
In short, "Eclipse" is the summer's preeminent date movie. Enjoy the TV spot, folks!
