It appears Solo: A Star Wars Story is going to include a couple more familiar faces, as Mark Hamill suggests R2-D2 and C-3PO will cameo in the upcoming spinoff.
Since then, they’re the only characters to appear in every live-action Star Wars movie to date.
Their roles have fluctuated between main players (the original trilogy) and brief cameo (Rogue One), but they’ve always been there.
If there was a Star Wars movie to break this tradition, Solo would be the most likely candidate.
