Doctor Who: The Return of Doctor Mysterio DVD Release Date
The DVD/Blu-ray will likely contain a behind-the-scenes documentary as with previous releases, but full details, as well as final artwork for the cover, have yet to be revealed.
You can pre-order it on Amazon UK right now, for £9.99 on DVD and £12.99 on Blu-ray at this page. The Return of Doctor Mysterio will be released on 23rd January 2017. If you're not a fan of the standalone releases, it'll likely be bundled into the eventual Series 10 boxset later in the year.
