Dimensions in Time

When The Dark Dimension production faltered, a more casual production was recorded instead. Dimensions in Time was filmed for charity on the sets for Eastenders, and featured both characters from that show and Doctor Who. Jon Pertwee, Peter Davison, Colin Baker and Sylvester McCoy all appeared as the Doctor, along with Tom Baker in a cameo at the start, many of the former companions, and Kate O'Mara's Rani as a villain.
