In an article on the official AMC Theatres website, three primary locations from the upcoming Solo: A Star Wars Story have been confirmed to be Corellia, Mimban, and Kessel.

Star Wars News Net goes into a bit more detail on these three planets for us: –

CORELLIA – AMC describes the planet, with the potential of the Empire scouting pod racers from the planet as prospective future TIE pilots.

It’s unclear how much of Solo will be set in Corellia, but certainly that’s where Han’s story will begin. There are strong rumors that the film will begin with Han as a pod-racer who catches the Empire’s eye and is drafted. Naturally, the life of an Imperial is unlikely to suit everyone’s favorite scoundrel.

MIMBAN- A planet once written about in the now non-canon novel Splinter of the Mind’s Eye, Mimban has been floated around as a concept for a few years now, originally set for use in Rogue One before it was replaced by Jedha. Here is what AMC has to say about the potential for this planet in the Han Solo film: –

LEGO sets for Solo have revealed the “Mimban Stormtroopers,” Stormtroopers wearing armor designed for the planet’s inhospitable swamp-and-jungle terrain. Clearly Solo will be heading to Mimban, although it’s unclear what role the planet will play in the film. It’s possible Han will actually be stationed there during his time with the Empire; it’s also possible that he’ll visit Mimban after leaving the Empire, given that the world had a thriving black market – ideal for a neophyte smuggler.

KESSEL – A planet referenced twice in the original Star Wars, fans always theorized Kessel would factor in to the Solo film, with the likelihood we’d finally see the famed Kessel Run. Even Ron Howard teased the planet with a not so cryptic tweet back in September — not really much of a surprise.

With a trailer hopefully due in the next week, we should be getting lots more information about the film in the coming weeks — we can only hope!
