The BBC has released new photos for the upcoming Doctor Who New Year’s Day special, Resolution.

Sadly, there’s no sign of the heavily-hinted-at Daleks, but this batch of pictures is at least more exciting than the previous bunch. We get to see some new locales, teasing a threat throughout the ages, plus a few guest stars.

Resolution airs on New Year’s Day on BBC1 and BBC America.
