The 63-year-old filmmaker took over control of the anthology movie after Christopher Miller and Phil Lord left due to creative differences with Disney and Lucasfilm, and since he began work he has drip fed fans with teaser photos from the set posted on his Instagram and Twitter accounts.

Now, Howard has posted a picture which seems to show a mysterious set of symbols carved into stone on crumbling ruins and more mysteriously, the filmmaker used the hashtag #McQuarrie.

He wrote: "Can anybody translate for me? #McQuarrie #UntitledHanSoloMovie (sic)"

The 'McQuarrie' hashtag is a direct reference to Ralph McQuarrie, the concept artist who designed initial looks for characters in the original 'Star Wars' trilogy.

Just last week, the filmmaker teased that his Han Solo spin-off film will feature the Millennium Falcon taking on the Kessel Run referenced in 'Star Wars: Episode IV - A New Hope'.

Howard has posted a picture which seems to show the Kessel Run - a hyperspace route used by smugglers to transport spice from the mines of Kessel - with the caption: "Spicey? (sic)"

Die-hard fans of the franchise will remember the scene set in Mos Eisley Cantina in the original 1977 movie when Obi-Wan Kenobi (Alec Guinness) and Luke Skywalker (Mark Hamill) question the credentials of Han Solo (Harrison Ford) and his Millennium Falcon Corellian freighter to get them and their droids R2-D2 and C-3PO to Alderaan to deliver the plans for the Death Star to the father of Princess Leia (Carrie Fisher) without attracting the attention of The Empire.

The Han Solo spin-off movie will focus on a younger version of the titular character, with Alden Ehrenreich taking over the iconic role from Ford.

Han and Chewbacca will be seen first meeting Lando Calrissian (Donald Glover) and they will also encounter Woody Harrelson's alter ego Beckett, who is believed to be a mentor to young Han who guides him on his journey to becoming a space smuggler.

The 'Star Wars Anthology' film is slated to be released in May 2018.
