Doctor Who Preview

The BBC has released a short prequel to the Doctor Who second-half premiere, “Let’s Kill Hitler,” which takes place directly after the events of the midseason finale.

This lead-in, written by Stephen Moffatt, underscores how dire the Doctor’s predicament is as the second half of the series kicks off.

Spoiler Alert: Don’t watch it if you’re not all caught up, because it rehashes the season’s biggest twist thus far.
