The one where the Eleventh Doctor makes an unexpected cameo...
Sometimes it's the little things that delight me most about Doctor Who. I think a lot of fans get enjoyment out of the silly little incidentals of their favourite show, those little moments that make them chuckle or get the hairs standing up on the back of the neck. Those private little moments that may mean nothing to everybody else, but which you always notice and treasure - your bits of Doctor Who!
I do enjoy the semi-regular feature in Doctor Who Magazine called Supporting Artist of the Month, which highlights some of the oft-missed performances by those uncredited people who mill about in the background, filling scenes and adding atmosphere. There's one particular supporting artist in this episode (who I think may well crop up in two different places) who I believe is a foreshadowing of a future Doctor! He's in the background of the studio scenes outside the Burrows warehouse, fiddling with equipment in a white coat (see picture on right). He looks the spitting image of Matt Smith! He possibly pops up again briefly in the scene where the US correspondent is reporting the news: he's busy on a phone, so it's hard to tell, but it looks like the same guy (and to be honest, I don't blame the other extra who crosses the screen, gently tapping him on the waist as he passes - is there more to these two supporting characters' relationship than we can ever know?).
