You’ve all seen the new Series 6 teaser, however you might not have all seen an alternative blink-and-you’ll-miss-it version which has also been airing across the BBC!

Although it doesn’t appear to be any different at first, if you look closely you’ll notice a mysterious figure standing behind the Doctor! Going by what we know, we can assume that it’s the alien he’ll be encountering in the opening two-parter. It was first seen at the end of the Christmas Day trailer, and it also appears in the prequel released today.

You can watch the alternative teaser below, just don’t blink! Look behind you, Doctor…
