The SFX site, the website of the science fiction magazine from Future Publishing, has a small handful of new photos from some recent filming done in Cardiff. "The Doctor Who production team are out and about filming on the streets of Cardiff again," says the report. "Our spies contacted us today to tell us that they had blocked off a street in Bute, near Cardiff Bay train station. We don't know which episode they're shooting, but because of the presence of soldiers in red caps, our guess is that they're filming pick-up shots for the two-parter 'Aliens Of London.'" You can see the photos on their site.
