Harry Potter and and the Goblet of Fire

I'd forgotten that The Doctor (AKA David Tennant) was Barty Crouch Jr.

Although, I shouldn't be surprised, since their tent at the Quidditch World Cup obviously demonstrates that they have mastered Time Lord science (Its bigger on the inside).

If only they'd gotten Christopher Eccleston to play the role of Voldemort, instead of that Fiennes character. I'm not yet sold on that Matt Smith guy. Although, I should get around to watching the second half of that season.
