Well, Solo’s budget was estimated to be around $275-300 million, so it didn’t even make that back with the domestic box office alone.
According to here, its worldwide box office was $390 million, combined with its project home release sales, you get a total of around $445 million.
Even Rogue One broke 1 billion at the box office alone. So Solo did not really perform well, not even close to the other anthology film.
Its performance definitely requires Disney/Lucasfilm to consider a few things. Did Solo underperform based on scheduling alone? Would it have gotten closer to that $1 billion if they had just pushed it to December, or was the story just not that much of a draw? If it was the latter, they will probably be more careful about which films they want to make theatrically. Apparently they were working on a “Tales from Mos Eisley” kind of film, but if Han Solo wasn’t enough of a draw, they need to figure out what attracts audience to a Star Wars project.
That’s why I personally think the success or failure of the Mandalorian is going to be crucial to Lucasfilm’s future. I think the tech Jon Favreau is using is pioneering. It could lower the cost of production for these visual effects heavy projects, paving the way for future Star Wars projects.
I’ve heard it described this way, but we could think of this coming winter season as the end of Phase 1. Once Episode IX is released, Star Wars will be moving on to brand new stories, and the Mandalorian will be the first of many such stories that have fewer ties to the Original Trilogy, which I think is necessary for the franchise’s growth.
I think fans want to see new stories. Saying that, despite Solo’s weak box office performance, it seems critically it has done fairly well, so those characters could still have a future on Disney+ as a series, which I would be interested in. Maybe it would do better there.
