Lacking in a TARDIS, David continues to progress through episodes chronologically. This time, both parts 1 & 2 of "Revenge of the Slitheen".
Things of note:
On further inspection it appears Coldfire Construction did not exist at the time of filming. I had misread my info.
New Slitheen suits may have been created for the show rather than ones reused from Doctor Who. However, with there never being more than two of the three adult Slitheen on screen simultaneously, as well as the reuse of the existing materials to create new Slitheen suits rather than a new monster from scratch, it's clear the budget was still limited.
The reason Mr Smith shows the Star Poet, Bane and Abbadon are because they are computer generated monsters rather than costume monsters and the 3D models for them are being displayed. (I think Abbadon is even t posing.) This may be very obvious to some but I was proud of myself for spotting it.
