Harrison Ford may have let slip a major Star Wars casting coup during an online promotional appearance earlier this month (13Apr14) when he appeared to be standing next to a director's chair with the name of his former castmate Carrie Fisher printed on it.

The former big screen sci-fi lovers were both in London, where the new Star Wars project recently began shooting, this past weekend (26&27Apr14) and now gossips are putting the pieces together and speculating the stars were there to shoot scenes as Han Solo and Princess Leia.

Disney executives behind Star Wars Vii have yet to comment on reports suggesting Fisher, Ford and Mark Hamill will reprise their characters in the film, but the franchise's creator, George Lucas, reportedly insisted on their involvement before selling the rights to the movie series in 2012.

And promoting new Tv docu-series Years of Living Dangerously on Reddit.com on 13 April (14), Ford appeared to drop the first hint when he was captured standing behind a director's chair with his name on it, next to one with the letters 'Ca' in view.

Gossips have since suggested the chair next to his is Fisher's.

Meanwhile, comedian Peter Serafinowicz, who voiced villain Darth Maul in 1999's Star Wars: Episode I - The Phantom Menace, has revealed he dined with Hamill on Sunday (27Apr14), posting a photo of himself with the original Luke Skywalker.

He tweeted, "Met up with @HamillHimself in London today. I wonder why he's here."
