'Doctor Who' fans have just about a month to wait before new episodes from the hotly anticipated second half of Season 6 air in the US.

To whet their appetite, the BBC and BBC America have released two new trailers, in which we are told "Something is happening to Time." Uh oh.

Why does the Doctor say his time is running out? Who is Winston Churchill pointing a gun at? Er, did Adolf Hitler just thank the Doctor, Amy and Rory for saving his life? And just why, exactly, is the Doctor trying to make out with Craig Owens (James Corden)?

Watch both trailers after the jump and see what you make of them.

When you're bombarded with one panel after the other, it's sometimes hard to figure out how to group them together. One writer I was sitting with at the BBC America panel, for instance, was blogging each individual panel, and was such a frantic blur of writing and Photoshopping that she developed what can best be described as SCTS (Sudden Carpal Tunnel Syndrome).

You gotta do what you gotta do, I guess. Me, I figured that there were three panels that could be put in what I call the "Comic-Con group": Spartacus on Starz, and Doctor Who and Being Human on BBC America. These shows got extensive showcases in San Diego over the weekend, and there wasn't many details revealed in any of these panels that you wouldn't have heard over the din at SDCC. So I'm going to go over the three of them in brief after the jump.

Let me give you a good teaser: If you were on the fence about seeing Spartacus, the prospect of a naked Lucy Lawless may convince you.
