It's one of the reasons why Plemons suddenly got super fucking fat for a couple of years. Star Wars basically is considered to be a gold ticket franchise, with regards to royalties and residuals. Ewan McGregor and Natalie Portman, for instance, got so rich off of the Prequels that they can now pick and chose what projects they do since they have Star Wars cash to live off of. He basically lost money that would have ensured he and his family would be set for life and allow him to do indie films and other passion projects.
Ironically, Plemons ended up dodging a huge bullet in a way. While Boyega was shitting up Star Wars with his ape face, Plemons did the second season of Fargo and received a huge amount of critical acclaim. And with Phillip Seymore Hoffman dead, he's become the defacto replacement for Hoffman for directors.
