From what I understand, this is definitely a good move as Lord and Miller were going for more of a goofy comedic (think what Gunn did with Star-Lord) approach to Han Solo, which didn't jive with Lawrence Kasdan and his son who wrote the script, in addition to LucasFilm producers.
Here's the official announcement:Â
RON HOWARD TO ASSUME DIRECTORIAL DUTIES ON THE UNTITLED HAN SOLO FILM
Lucasfilm is pleased to announce that Academy Award-winning filmmaker Ron Howard has been named director of the untitled Han Solo film.
â€śAt Lucasfilm, we believe the highest goal of each film is to delight, carrying forward the spirit of the saga that George Lucas began forty years ago,â€ť said Kathleen Kennedy, president of Lucasfilm. â€śWith that in mind, weâ€™re thrilled to announce that Ron Howard will step in to direct the untitled Han Solo film. We have a wonderful script, an incredible cast and crew, and the absolute commitment to make a great movie. Filming will resume the 10th of July.â€ť
Howard has made some of the biggest hits and most critically-acclaimed movies of the modern era. Among his many films are Lucasfilmâ€™s Willow, Apollo 13, A Beautiful Mind (winner of four Academy Awards, including Best Picture and Best Director), The Da Vinci Code, Frost/Nixon, and Rush. He also narrated and produced the beloved comedy series Arrested Development, starred in George Lucasâ€™ American Graffiti, and remains a TV icon for his roles in The Andy Griffith Show and Happy Days.
The untitled Han Solo film is slated for a May 25, 2018, release.
