Here's why Disney is demanding reshoots of the 'Star Wars' spin-off

After Tuesday's news that the first-ever "Star Wars" spin-off, "Rogue One: A Star Wars Story," will undergo four weeks of reshoots after Disney executives saw the movie and were "not happy" with the current version, new details have surfaced on what exactly was in the cut.

A source told The Hollywood Reporter that the movie didn't have the "classic" feel of a "Star Wars" movie and that it felt more like "a war movie."

The goal is to add in some fun to the adventure. That's something many movie studios want their tentpoles to have following the success of "Deadpool" and "Captain America: Civil War," which both executed their action and drama with a lighthearted touch, and cashed in at the global box office to the tune of about $760 million and $1 billion, respectively.

Though not confirmed, reshoots could also open the door for a cameo from young Han Solo, a role recently handed to actor Alden Ehrenreich ("Hail, Caesar!").

The source also told THR that "Rogue One" will literally end right before the events of the original "Star Wars."

"This takes place just before 'A New Hope' and leads up to the 10 minutes before that classic film begins," the source said.

If this is correct, the plans for the Death Star that Jyn Erso (Felicity Jones) and her team are after in "Rogue One" are the same plans that link Luke, Han, Leia, and Obi-Wan in the start of "A New Hope."

"Rogue One" opens in theaters December 16.
