The one with lots of greenscreening.

Investigating the planet, the Doctor and Leela are awkwardly projected onto a photo background and find a system of caves that leads to the [=P7E=], long ago buried by asteroids. The [=P7E=]'s computer, Oracle, has gone insane and rules over the survivors of the Minyan crew with the aid of the robotic Seers. It allows Jackson to take the race banks, but the Doctor realises that they are just fakes, primed with fission grenades. The Doctor herds the [=P7E=]'s descendants into the [=R1C=] and gives Jackson a rather grand WhatTheHellHero speech for considering the quest more important than the actual people the quest was all about. After that, Four tricks Oracle into allowing him to take the real race banks, meanwhile returning the fakes via the Seers. The resulting explosion destroys the [=P7E=] and propels the [=R1C=] off on its voyage to Minyos II with the [=P7E=]'s survivors.

* FacelessGoons: The guards. And even when they take off their helmets, their faces don't actually look like faces.

The end result of the former showrunner Philip Hinchcliffe [[WriterRevolt getting even with the higher-ups in retaliation for being kicked out of the saddle]] by devouring the show's budget last season, ''Underworld'' is perhaps the most infamous case of NoBudget on the classic series. Without the funds to create sets, most of the scenes portrayed in it are almost entirely reliant on GreenScreen effects. The end result? What remains today one of the most hysterically shoestring stories of the original run.

* ShoutOut: Part one was broadcast only a few days after ''Series/BlakesSeven'' debuted. Composer Dudley Simpson worked on both shows and, according to the DVD production notes, snuck a reference to the theme music into the score for Underworld.

* ArtisticLicencePhysics: Most physics in this episode depends on a rather substantially overestimated gravitational constant.

* BeneathTheEarth: The reason for the episode's title, rather than, well, TheUnderworld.

* NegativeSpaceWedgie: The spiral nebula at the beginning of the episode.

* MadeASlave: Most of the people on the planet are enslaved to labor. They think the "sky falls" (tunnel collapses) are done to keep their number low, just enough to labor.

* GettingCrapPastTheRadar: According to the Doctor:
-->What is blown can be sucked.

* FrickingLaserBeams: The weapons used are lasers combined with particle beams.
