The BBC have released a lead of new promotional images and still from this weekends episode Journey to the Centre of the TARDIS which will air at 6.30 on Saturday April 28th on BBC One and on Sunday April 29th at 7.30 on ABC 1.
There is one spoiler-y picture towards the end so be warned.
(Note: I’m still trying to find the best way to upload images to the site, I’m not very happy with the current method so I’ll probably change it soon)
