==Behind The Scenes==
This would pretty much replicate the form by Sentai/Rider of having a late Autumn/early Winter movie before the expected Christmas special where in this feature movie, the worlds of Doctor Who and Sherlock would unite for a journey across time and space to solve a murder mystery. However unlike the summer movie, this one would be somewhat shorter.***
