Fox/Lucasfilm/Disney should re-release Star Wars: A New Hope...
Theatrically.
Whether it is the completely original version, fully restored...the current 'special edition' or some sort of brand new 4K restoration that keeps the visual/cosmetic improvements but ditches the annoying 'creative changes'.....they should do it.
40th anniversary of the original film is coming up. You re-release that film in theaters, globally, in 3D even...give it a solid marketing push...and you're sure to more than make back your investment.
Coming off of the heels of Rogue One is actually perfect timing considering the end of that film.
Heck...they could even time re-release of Episode 4, 5, 6, and 7 to build up to Episode 8 in December.
If Star Wars has anything it is brand loyalty...and hot off the heels of Rogue One, celebrating the 40th anniversary of the original film, and maybe giving the fans a version of the film that doesn't have all of the added CGI creatures and Greedo shooting first.....fans would turn out in droves.
