BBC has released an awesome new trailer for the sixth season of “Doctor Who” on their site. It covers the second half of the series, episodes 8-13.

The second half of the series begins with Let’s Kill Hitler, written by Steven Moffat and directed by Richard Senior. And judging from the snippets we’ve seen so far, future adventures will feature Cybermen, the Silence plus the return of River, looking a little different…

There is still no word on when fans can expect the series to return on BBC. But, rest assure, “Doctor Who” will return to BBC America on August 27.
