The Doctor and Martha arrive in present day Cardiff to refuel the TARDIS and are inexplicably thrust to a distant planet 100 trillion years into the future. When they arrive they realize they have an unexpected passenger in Captain Jack Harkness who has been patiently waiting for the Doctor's return since the mid-19th century. On the planet they eventually meet Professor Yana who is running the 1000-year old Utopia project, the aim of which is to relocate the human-like creatures to a new planet, away from the outsiders who they fear they will become if they don't leave. When Prof. Yana has need of someone to make repairs in a room in which no one can survive, the Doctor has the perfect candidate. The Professor is not what he seems to be however and Martha notices he has a fob watch much like one the Doctor recently made use of. Written by garykmcd

Did You Know?


The Doctor's response to the Master asking him to "use my name" was originally intended to reveal who Yana really was, but the writing team decided it would be a pity to have Derek Jacobi not be able to utter his catchphrase during his brief stint as the character. See more »


After Chantho fires a pistol at Professor Yana as he's about to board the TARDIS, as she collapses, you can see a part of the prop pistol's handle snap off. See more »


The Professor: Killed by an insect. A girl. How inappropriate. Still, if The Doctor can be young and strong, then so can I. The Master reborn!

A Utopia of Quality!
7 February 2019 | by A_Kind_Of_CineMagicSee all my reviews

This continues a run of tremendous top quality stories. The majority of the episode is subtle in its qualities but is unquestionably excellent throughout before reaching an electrifyingly exciting last 10 minutes as at the end it re-introduces one of the Doctor's greatest enemies in the most thrilling way.

The writing of the whole episode is brilliant with an engaging script which has humour, intrigue, touching drama and dystopian futuristic ideas. Derek Jacobi, one of the great actors of our time, puts in one of the best guest starring performances in the show's history. The full range shown by Jacobi as he portrays different sides of the character is sensational. He is beautifully endearing before building towards very moving moments as he struggles with memories hidden deep inside and then a dazzling different side is shown in the heart thumping final scenes.

David Tennant shows yet another awesome display in his top standard performance as the Doctor, Freema Agyeman yet again proves to be a perfect companion, John Barrowman makes a very welcome and impressive return as Captain Jack Harkness and all other acting, direction and production values are great. Graeme Harper the director also directed 42 earlier in this series as well as the top 10 classic The Caves of Androzani from the 5th Doctor's era. He shows his quality yet again.

There is a nice link in to themes interwoven through the series involving the Doctor's watch in the wonderful Human Nature/The Family of Blood and The Face of Boe from Gridlock as well as leading on with the cliffhanger into the final two parter that finishes Series 3.

The whole story, especially with the terrific ending makes this a 10/10 cracker.
