Did You Know?


Various references to River Song's past with the Doctor are scattered about. Amongst them are her blue 'call box' diary. See more »


In her first appearance in the series, River questions the Tenth Doctor about the crash of the Byzantium, an adventure she shared with the Eleventh Doctor. While this makes sense if she is mistaking the Tenth Doctor for a Twelfth or later incarnation, her photo collection in this story has all of the prior Doctors in chronological order. This, coupled with her insistence that the photos are the only incarnations of the Doctor, implies that she does know the correct order, and therefore would also know that the Tenth Doctor would have no memory of the Byzantium.

River Song: I'm so sorry. This is my husband, Ramone.
The Doctor: Another one? Are you going to kill him, too?
Ramone: We're not actually married.
River Song: Ah, we are, in fact. I wiped it from your memory.
Ramone: Why?
River Song: Well, you were being annoying.

Changes to the opening credits were made for this Christmas time episode. There are added snowstorm effects that the Tardis flies through and in addition the circling 'planets' (visible just after the Alex Kingston credit) are in fact Christmas ornaments. See more »

Perfect For A Christmas Day
18 March 2018 | by StuOzSee all my reviews

Doctor Who (Peter Capaldi) and the lovable lady called River Song team up.

This episode is the perfect example of why Capaldi is better than all other Doctor Who actors before him. In a nutshell: I watched this episode last night and now all I remember is the wonderful comedy of it all (between Capaldi and River Song).

All I remember about the plot was that big red thing that looked like the Robinson robot in the Lost In Space movie of 1998. Everything else was comedy, comedy and it was very funny!

If the previous Doctor Who actors tried to do a show like this the hour they would not have been as effective. Only Capaldi could pull this off so well. I am not saying the other Who actors were unfunny, just that their humour could never carry a whole episode like this.

So this hour is perfectly matched to a bright Christmas Day, it is highly recommended!
