Matt Smith appears as the Eleventh Doctor via pre-filmed segments due to scheduling conflicts with the ongoing filming of the main series at the time of the show's touring.
After showing off the different monsters he has captured, Vorgenson pulls Winston Churchill from World War II, causing a paradox and threatening the present.
Churchill is sent back to the Minimiser, and Vorgenson summons Judoon to track down the Doctor in case he has already arrived.
The Doctor contacts the audience and attempts to have them help him summon his time machine, the TARDIS, to him, but is interrupted by Weeping Angels emerging from the Minimiser.
The Daleks appear, and they reveal that they were the ones that gave Vorgenson the concept for the Minimiser by projecting the ideas into his dreams.
[3] In discussions with Doctor Who executive producer Steven Moffat, Brenton proposed a "Jurassic Park kind of feel, with this character who's reeling out these characters"; Moffat suggested that the show could follow on from elements of the 1973 Doctor Who television serial Carnival of Monsters, which featured an interstellar showman who kept different monsters miniaturised for entertainment.
[2] Ben Foster, who orchestrates Murray Gold's compositions for the television programme, developed the musical component of the show, and conducts the 16-piece band.
[6] Several antagonists from throughout the series appear as part of the show, including the Judoon, Clockwork Robots, Silurians, Weeping Angels, Cybermen, Daleks, and Scarecrows.
[7] Pete Dillion-Trenchard, writing for Den of Geek, praised the performances of Smith, Planer, and Briggs, as well as the final scene with the Daleks.
[1] Paul Simpson, writing for Total Sci-Fi Online, praised the show's production and performances, as well as the music score from Foster.
[5] Dan Martin, writing for The Guardian, also found the production to be more fitting for younger audiences, but praised the usage of elements from the series, such as the monsters, music, and pre-filmed segment featuring Smith.
