'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.
