WHAT TO EXPECT FROM THE NEW STAR WARS FILM! Rogue One - A Star Wars Story, Analysis

I don't know about you all but seeing this teaser trailer gave me goosebumps...  this teaser trailer kind of got us by surprise it hasn't even being a year since Star Wars the Force awakens was released in December so it's a bit of a surprise that so fast another Star Wars movie is  coming out.  So a lot of you might be wondering what this movie is about  and we're in the Star Wars timeline is this movie located.

TIMELINE 
Following the foundation of the Galactic Empire a wayward band of Rebel Fighters come together to carry out a desperate mission to steal the plans for the Dead start before it can be used to enforce the  Emperor's rule (synopsis)
 As you can see from the teaser trailer,  this Star Wars film is set at the start of the Rebellion right after episode 3 and in between episode 4.  You might remember in the film episode 4 A New Hope  that the Rebellion managed to steal the Death Star plans and then plan an attack to destroy it.   Well apparently this movie is set to tell the story of how and who stole those plans to destroy the Death Star. 
 This is why in the trailer you can see the old style Stormtroopers and the Death Star which was destroyed at the End of Episode 4  A New Hope
 It is awesome that we get to experience again the classic style of Star Wars.  According to  online resources we are expected to see Darth Vader and possibly other characters that were in the original trilogy.

so if this explanation wasn't enough here is a picture timeline so you can see what I mean...

THE CAST 
In the trailer we can see some recognizable faces like
 Felicity Jones as Jyn Erso
 Diego Luna as a rebel captain
 Riz Ahmed as Bodhi Rook
 Ben mendelsohn as an imperial Admiral
 And many many more characters that have not yet been announced

It is possible that we might get to see some other new characters or creatures from past films so be vigilant when watching this new movie in December you might miss some cool old Star Wars characters

 I don't know about you guys but I am really excited about this movie because it's going to give us a better view of what happened right after Anakin Skywalker became Darth Vader and Chancellor Palpatine became the emperor and  how this Rebellion started. 
 I am pretty sure this is just going to be a small  almost 2 hour movie  just to give us more insight on how the Rebellion got to the point where it is in episode 4 A New Hope
