In June last year the two filmmakers announced they were leaving Solo: A Star Wars Story over “creative differences” with Lucasfilm president Kennedy and screenwriter Lawrence Kasdan.
Now the Star Wars boss has given clarifications regarding why she had to make the decision to replace them with Ron Howard.
Speaking with Entertainment Weekly, she said: “I think these guys are hilarious, but they come from a background of animation and sketch comedy.
“And when you are making these movies you can do that and there’s plenty of room for improvisation, we do that all the time.”
Kennedy continued: “But it has to be inside of a highly structured process or you can’t get the work done and you can’t move the armies of people to anticipate and have things ready. So, it literally came down to process. Just getting it done.
“There comes a point where there’s only so much you can do and then you have to take a different course and that’s where we ended up.
“So, it’s not like there’s anything I can really add to it because the last thing I want to do is…[reopen a wound].”
“Yeah, I just don’t want to do that. These are really great guys and you know, nobody wanted this to happen. It was just one of those unfortunate things.”
Some fans felt he didn’t sound or look enough like a young Harrison Ford.
Solo: A Star Wars Story will be released in UK cinemas on May 25, 2018.
