[Mild SPOILERS for Star Wars: The Force Awakens ahead.]
Star Wars: Episode VII - The Force Awakens serves as the beginning of a new Star Wars movie trilogy set over thirty years following the events of Episode VI - Return of the Jedi. J.J. Abrams' Star Wars film in turn picks up in a time when the deeds of original trilogy heroes Luke (Mark Hamill), Leia (Carrie Fisher), and Han (Harrison Ford) have become the stuff of legend.
That's especially true for younger people in a galaxy far, far away, who has either only heard the stories from second-hand sources or heard distorted versions spread by The First Order: the organization that seeks to succeed where the Galactic Empire failed. However, moviegoers will be brought up to speed on what life is like in the Star Wars galaxy in The Force Awakens from the vantage points of such younger characters as Jakku spaceship scavenger Rey (Daisy Ridley), the First Order stormtrooper who's known as simply Finn (John Boyega), and the Resistance X-Wing pilot Poe Dameron (Oscar Isaac).
Poe Dameron recently got his own Force Awakens character poster, and Isaac (speaking in Spanish) introduces the newly-released Star Wars TV spot that's been featured, above. Moreover, during the Star Wars: The Force Awakens press junket day, Isaac revealed the following about Poe's history (h/t Variety) - specifically, how the actor played a role in crafting a backstory for the character has since become part of the franchise canon, thanks to the comic book series "Star Wars: Shattered Empire":
“After we started filming, I was talking a bit about where could Poe have been. At the very end of ‘New Hope,’ the medal ceremony, one of Guatemala’s claims to fame is that that last shot where the ships are leaving, where you see the temples, was shot in Guatemala. For me, the fact that I was born there and that’s a rebel base and I’m playing a Resistance fighter, maybe Poe was there, that’s where he’s from, and then this comic book comes out in ‘Shattered Empire’ where Poe’s parents ended up going to Yavin 4 and making sweet love. So that’s an amazing thing, if the first time you’re talking about where your character’s gonna come from, ends up in a comic book … it feels like we’re creating these things together.”
Interestingly, Dameron is the only one of the four pivotal new players featured in The Force Awakens - including Kylo Ren (Adam Driver) who belongs to a group of Dark Side of the Force users known as the Knights of Ren - whose last name is for certain known; and thus, he is the only one whose connection to other characters in the Star Wars universe (or lack thereof) is firmly established. This is no accident, of course, but proper answers aren't going to be provided to those questions until The Force Awakens hits theaters - and even then, the film will no doubt leave certain elements open for further exploration in future movies.
On that note - check out another new Force Awakens TV spot, with more footage from Rey and Finn's adventures with BB-8, Han, and Chewbacca (Peter Mayhew) aboard the Millennium Falcon.
