A complete aside.  BBC America ran a movie about the making of the first few seasons of Dr. Who last night.  It was both entertaining and informative about how TV shows were made in the early '60s.  And the Matt Smith appearance in it was pretty good.  Poignant, actually, when you consider that the first actor to play the Doctor felt that the show had the potential to run "forever"--at least, the other actors said he told them that.<br/><br/>Anyway, more about TV from the '60s.<br/>
