The film also marks the shortest period between Star Wars movies. While each of the original and prequel trilogy films were separated by three years, more recently fans have been getting a new hit of Star Wars each December.
Last December's The Last Jedi, episode eight in the main saga, was a mixed success for Disney. Its global box office of $US1.3 billion made it the ninth-highest grossing film of all time (at the time; it has since been bumped to 10th place by Marvel's The Black Panther) but significantly below episode seven's global box office taking of just over $2 billion.
Some diehard fans also criticised elements of The Last Jedi, particularly its PC sensibilities.
Will Solo win back the disaffected fans? The first indication will come on May 15, when Solo premieres at the Cannes Film Festival.
It will screen in cinemas around the world from May 25.
