Catalyst is the prequel novel to Star Wars anthology film, Rogue One: A Star Wars Story.
It was announced by Del Rey at Chicago's C2E2 on 18 March 2016. The author was initially withheld, but was finally revealed to be James Luceno at Star Wars Celebration London in July 2016, along with the official cover image.
Rebel Rising is a young adult novel by Beth Revis. It is set between the prelude and first act of the spin-off film Rogue One: A Star Wars Story, and follows a young Jyn Erso during her time with the renegade Saw Gerrera.
Rogue One (subtitled "A Star Wars Story"), is the first in a planned series of Star Wars spin-off films, originally referred to as "anthology films".
Rogue One is set shortly before the events of Star Wars Episode IV: A New Hope, and will follow a group of rebel spies as they attempt to steal the plans for the Galactic Empire's first Death Star superweapon.
Filming took place at Elstree Studies near London between August 2015 and February 2016, with reshoots taking place in June 2016. Alexandre Desplat, who previously worked with Edwards on Godzilla was originally slated to score the film, but due to production delays he was no longer available and was replaced by Michael Giacchino once he had finished up on Marvel's Doctor Strange.
So they've apparently auditioned over 2500 people for the role of young Han. Some famous names have been attached to this (including Dave Franco, Aaron Taylor-Johnson, Miles Teller, and Rami Malek)... but I really hope they go with a relative unknown for the role. Someone with a resemblance to Harrison/Han, but not a body double... who can pull off his sarcastic charm.
And also, I wonder if this will involve the new plot revelation from a recent comic in which Han had seemingly been married in the past before meeting Leia. I suppose it all depends on when it happened and why and how long it lasted and etc.
