Heres what we know now: Several sources close to the movie and others close to the directors tell EW that ever since filming began back in February, Lord and Miller, who are known primarily for wry, self-referential comedies like 21 Jump Street and the pilot episodes for Brooklyn 99 and Last Man on Earth, began steering the Han Solo movie more into the genre of comedy than space fantasy.
Apparently, the split was a subtle one that became magnified over time: Lucasfilm and producer Kennedy believed Lord and Miller were hired to add a comedic touch; Lord and Miller believed they were hired to make a comedy.
Its an ironic turn. Last year, when Rogue One was undergoing reshoots, fans were critical because they assumed Lucasfilm was trying to lighten the war story with more comedy. Those concerns were unfounded, but now the opposite is the case for the Han Solo film: Lucasfilm wants young Han Solo to be more grounded.
