Ron Howard shares mysterious, on-set image from Han Solo spinoff film

Oct. 10 (UPI) -- Ron Howard has shared on Instagram another on-set image from his upcoming Star Wars standalone film about a young Han Solo.

"Tough neighborhoods contain Doorways to adventure, mystery & excitement #UntitledHanSoloMovie," the filmmaker wrote alongside a mysterious image that appears to resemble a entrance or doorway full of blue lighting.

The on-set photo is the latest tease shared by Howard who previously gave fans a hint that the Kessel Run mentioned throughout Star Wars lore would be making an appearance in the film, along with a small taste of how Donald Glover will look as Lando Calrissian in the film and a glimpse at a new droid.

Howard took over directing duties on the film in June in place of filmmakers Phil Lord and Christopher Miller who were booted off the project over "different creative visions."

The film also stars Alden Ehrenreich as Han Solo, along with Emilia Clarke, Woody Harrelson and Thandie Newton. The untitled Han Solo film is set to open in theaters on May 25, 2018.

On Sunday, Howard released a photo of the editing room he uses to work on the film writing, "Spending more time in the editing rooms each day now after we wrap shooting."

The 63-year-old followed up that tweet by responding to a fans comment about the film perhaps being almost finished. "Almost finished shooting but months of post production work ahead. Tremendous team so lots to look forward to creatively," Howard said.
