'Pint of Stella and a Star Wars script! That's me sorted till five,' actor writes, in seeming follow-up to interview gaffe last year

Lock, Stock and Two Smoking Barrels star Jason Flemyng has become the latest British actor to confirm an audition for the new Star Wars film after posting a snap of what appears to be his copy of the script on Instagram.

The famously loose-lipped Londoner accompanied the photograph, since removed, with the words: "Pint of Stella and Star Wars script! That's me sorted till 5!"

Flemyng, 47, was believed to have been in line for a role in Star Wars: Episode VII during a period when his regular collaborator Matthew Vaughn was being considered for the director's seat. Star Trek's JJ Abrams was eventually handed the high-profile job of reviving the classic space opera, but Flemyng looks like he's still in the running for a part. Or at least probably was, until someone at Disney saw how swiftly the Instagram post had spread across the blogosphere.

Flemyng's script is the same colour as those in a photograph of a pile of screenplays posted by Abrams' production company in July, which were widely thought to be for Episode VII. But he may come to regret his actions. Irish actor Saoirse Ronan lamented her loquaciousness recently after revealing her audition publicly, only to be told she had not won a part. "I just shouldn't have said anything," she told the Playlist. "I just auditioned for it, like everyone else did. To pretend that you have a lightsaber in a scene is always very exciting. It would be great. But it's something that everyone's gone up for."

Flemyng has form with this sort of thing. In November, he accidentally "revealed" that Vaughn was in the hunt for Episode VII while being interviewed at the UK premiere for crime romp Seven Psychopaths.

Other actors from the UK who have been linked to Abrams' film include Benedict Cumberbatch, Chiwetel Ejiofor and Simon Pegg. It was reported today by the Bleeding Cool blog that outgoing Doctor Who Matt Smith could also be in the running.

Series veterans Mark Hamill (Luke Skywalker), Carrie Fisher (Princess Leia) and Harrison Ford (Han Solo) have all been tipped to return for Episode VII, but Disney has not yet confirmed any casting or plot details. So far, the studio has revealed only that diminutive droid R2D2 will definitely be back.

Yahoo Movies has had a pretty good crack at deciphering some of the material in Flemyng's script. Apparently it centres on two characters named "John" and "Will", who are out scavenging.

Episode VII is the first in a new trilogy planned by Disney after the studio bought all rights to the long-running space opera for $4.05bn in October last year. It is shooting in London early next year for a cinematic release date of Christmas 2015.
