Thanks to the wonderful people who spend hours on end hiding behind cars and cameras to bring US the pictures we want of the starts filming the new series of Doctor Who we now have PROOF that Alex Kingston will be returning as Professor River Song in the Series 31 (for, on here, that is what it will be called) finale.
All credit goes to one of Gallifrey Base's fantastic set reporters, "Asti", who took this photo of the crew filming at Swasnea's Guildhall. You can see more photos by Asti in the Set Report thread on Gallifrey Base by following the link on the left of this page.
We've already had pictures of her filming on a beach wearing a very nice evening dress and, later, army camouflage. The trailer shown after Matt's first performance also shows a very brief glimpse of River falling ONTO The Doctor inside the newly designed TARDIS console room (I think). This lends to the rumour that River will be more than just a guest star for her two parter, which set reports suggest feature the return of another of Steven Moffat's creations, the Weeping Angels, last seen in Blink, RTD's third series 'Doctor-Lite' episode.
Also spotted was Gavin and Stacey's "Gwen", Melanie Walters, although as of yet we have no information on who she is playing...
More to come on this, no doubt! So stay tuned!
