Celebration Panel Announces "Star Wars: Rogue One" Film

In case you missed it, Disney announced at the Star Wars Celebration that they will be starting a line of individual movies about Star Wars characters - taking a page from the Marvel franchise.  They announced that the first film would be entitled: Star Wars Anthology: Rogue One and showed a teaser trailer to excited audiences.

In case you're wondering where the trailers are, YouTube took them down - except for two:

The first is someone filming the trailer from their cell phone camera at the announcement

The second is a very creative re-rendering of the trailer with LEGOs:

So is this really a good idea?

Should we have standalone Star Wars films about the characters we don't even know yet?  Perhaps they will have cameos by our favorites?  Let me know what you think in the comments.

Set to release in December of 2016, it will be directed by Gareth Edwards who also directed last year's Godzilla.   The only confirmed cast members are Felicity Jones and Ben Mendelsohn, neither of whom are in listed as starring in Star Wars: The Force Awakens.  Sam Claflin (known for his portrayal of Finnick Odair in The Hunger Games: Catching Fire and The Hunger Games: Mocking Jay Part 1) and Riz Ahmed (Four Lions and Centurion) are rumored to be cast but there are no parts listed by anyone's name.

Do we really want a Marvel version of Star Wars?  I'm not knocking having Star Wars come to theaters again, but I do not want another craptastic set of movies that was the prequels disaster (especially Episode II).

What do you think?
