This Ad is mind-blowing set in Liverpool which is an alternate dimension it stars kyle Mclaughlin,John Pertwee and is narrated by Paul Darrow some of Sci-fis greatest in 60 seconds
the person who did that warning in the ad was Paul Darrow who played Avon in Blake's Seven and was in the Who serials Doctor Who and the Silurians (1970) and Timelash (1985)
It’s my personal headcanon that The Doctor has The TARDIS , The Whomobile, and Bessie all side by side in there, and they all fit in quite comfortably because his garage is bigger on the inside.
