According to Collider, Lucasfilm have put the two Star Wars spin-off movies they have in active development - one focusing on Obi-Wan Kenobi and another about Boba Fett - on indefinite hold, apparently in response to the disappointing box office of Solo: A Star Wars Story.
Solo launched a month ago to stronger-than-expected reviews (given the film's troubled and expensive production history), with especially strong notices given for man-of-the-moment Donald Glover's performance as Lando Calrissian. However, these failed to convince an audience that appeared to be sceptical of the need for a Han Solo origin story and was blockbustered out, having been hit by The Avengers: Infinity War and Deadpool 2 in just the preceding few weeks. With Star Wars Episode VIII: The Last Jedi only hitting cinemas five months earlier, there was also talk of "franchise fatigue" setting in.
Cinema chain owners have blamed the May release date, several apparently having urged Disney to move the film to December. It is possible that Disney deliberately targeted this movie for May as an early test to see if audiences would be prepared to see multiple Star Wars movies in a year, as they do with the Marvel Cinematic Universe, in preparation for a future increase in production cycles. If that test was the goal, clearly it has failed.
Whatever the explanation, the effects have been sobering for Disney's bottom line: in its first month on release, Solo has garnered a spectacularly low $350 million. This has meant that the film has broken even with its production budget, but has not come close to making back its marketing budget (for comparison's sake, all three previous Star Wars movies needed to make back triple their production budget before becoming profitable) and will now need healthy media sales and streamings to become profitable, which may take another year or so.
The Obi-Wan and Boba Fett movies are on hold now whilst Lucasfilm reassess the appeal of those movies: although fans seemed keen to see Ewan McGregor take on the role of Obi-Wan in a competently-directed and written film, news of a Boba Fett film was greeted with utter apathy when it was revealed last month. There also appears to be a strong blowback amongst even casual fans against the endless parade of prequels being announced. A key difference between the Star Wars and Marvel franchises is that the Marvel movies all take place in the same timeline and continuity, with characters crossing over from one to another and each contributing to a larger whole (people who loved Black Panther, for example, were thrilled to see those characters and storylines continuing just a few weeks later in Infinity War). Star Wars has not been doing that, with the prequel side-movies being seen as disposable compared to the main saga films.
Perhaps with this in mind, Disney and Lucasfilm are refocusing their attention on Star Wars Episode IX, which is shooting now with J.J. Abrams wrapping up the story of Rey, Finn, Poe and Kylo Ren that he began in The Force Awakens and is due to hit cinemas in December 2019. Rian Johnson is also developing a new Star Wars trilogy and Game of Thrones producer-writers David Benioff and D.B. Weiss are also developing ideas for a new multi-film series. These two projects remain in active development (although neither is formally greenlit yet).
Whatever the situation, Disney recently turned a profit on their overall Lucasfilm deal, so the $4 billion investment they made in the franchise in 2012 has now come good, but there may be some at Disney who were expecting a much bigger success from the franchise. As some fans have indicated, maybe the golden goose has been squeezed dry and Lucasfilm may be advised to let the franchise rest for a few years after Episode IX?
