Doctor Who is set to feature Nazi dictator Adolf Hitler in a forthcoming episode, it has been reported.
The BBC One sci-fi show, back on our screens in September, has released a trailer which appears to depict Matt Smith's character in 1930s Berlin.
In it we see Hitler, played by Albert Welling, and the Nazi Swastika sign, and it is thought that the Doctor plays a part in his downfall, reports the Daily Mirror.
The trailer played at Comic-Con in California, where it attracted a mixed reaction.
It is also rumoured that the Doctor's arch nemesis the Master will return in this episode.
