BD posted this little bit of a special Weakest Link episode featuring various Doctor Who (current) actors, including David Tennant and John Barrowman. Turns out the whole show is actually online here: 1, 2, 3, 4, 5.
It’s not quite as exciting as the Satellite Five version of the show, and the actual question bits are pretty … lame, to begin with, though they get a lot better as time (and space) goes on. But there’s some amusement now and again, including John Barrowman’s rendition of the Doctor Who theme … plus some outtakes.
Woot!
You found them all. :)
