While the new Han Solo Star Wars anthology film charges on with last-minute replacement director Ron Howard, a new report has emerged that Lucasfilm was not only dissatisfied by the direction under Phil Lord and Chris Miller, but also the performance of the young Han Solo by Hail, Caesar!'s Alden Ehrenreich.

According to The Hollywood Reporter, Lucasfilm decided to hire an acting coach for Ehrenreich late into the film's production, with the intent of getting a better performance from the leading man.

Ehrenreich's acting coach wasn't the only late-stage hire -- the project’s editor, Chris Dickens, was replaced by frequent Ridley Scott collaborator Pietro Scalia.

Regardless of the changes, the directors still couldn't make it work with Lucasfilm, as their improvisational style jarred with the large-scale demands of the studio. Lawrence Kasdan, the film's co-writer, reportedly told Lord and Miller to stick to the script. And, after continued tension, the directors inevitably departed the project after they were fired by Lucasfilm President Kathleen Kennedy.

It's still up in the air if Lord and Miller will retain a directors' credit on the project, considering they shot almost five months worth of footage. Entertainment lawyer Bryan Sullivan indicated to TheWrap last week that the studio “is obligated to give them credits, but it’s a question about how much work has been done.”

Regarding Lord and Miller’s departure from the project, Lucasfilm president Kathleen Kennedy had said, “Phil Lord and Christopher Miller are talented filmmakers who have assembled an incredible cast and crew, but it’s become clear that we had different creative visions on this film, and we’ve decided to part ways. A new director will be announced soon.” The director has now been confirmed to be Howard.

“Unfortunately, our vision and process weren’t aligned with our partners on this project. We normally aren’t fans of the phrase ‘creative differences’ but for once this cliché is true. We are really proud of the amazing and world-class work of our cast and crew,” explained former directors Phil Lord and Christopher Miller.
