Ron Howard and George Lucas, who have collaborated several times.
The film is still on track for release on 25 May 2018, just five months after Star Wars Episode VIII: The Last Jedi hits cinemas in December, although delays are likely if the production team decide more significant reshoots are needed.
Although Howard hasn't been involved in a Star Wars project before, he did star in George Lucas's 1973 movie American Graffiti (alongside a young Harrison Ford) which led to his casting in the sitcom Happy Days and kickstarted his Hollywood career, including collaborating on the movie Willow with Lucas, so there is some synchronicity involved in this news.
Rumours that Howard has said, at any point, "Hold my beer," and "I got this," have yet to be confirmed.
