I was expecting the trailer to be the audio from Guardians of the Galaxy synced over Star Wars clips, but The Unusual Suspect took my expectations and lit them on fire. The trailer is so much better than that. It opens with the same background music as the GotG trailer, but instead of Peter Quill's voice, we're greeted by none other than Luke Skyewalker. "Allow me to introduce myself," Luke says. Cut to Luke lightsaber fighting. "I am a Jedi."
The trailer has expertly recut the Star Wars films to give the appearance of one feature length space comedy, coming to theaters May 1977. I don't know if that means that tickets are avaible for retroactive presale, but I would definitely check Fandango.
Check out the mock-trailer for more of Luke kicking butt, Han Solo being Han, light-saber fights, and lots of laser gun firing. While "Spirit in the Sky" and "Hooked on a Feeling" play in the background, of course.
