- Angst? What Angst?: The first ever companion deaths in the series are encountered- that of Sara Kingdom and Katarina. Is the Doctor depressed about this? Broken, that after taking up Barbara and Ian so long ago to travel in space in time, that a human died in his helpless hands? No. He shakes his head, says goodbye, and moves on.
- Big-Lipped Alligator Moment: "The Feast of Steven" has our heroes picked up by police on Christmas, getting split up on a Roaring Twenties movie set, and finally breaking the fourth wall. It should perhaps be noted that there was a good reason for this. The episode was broadcast on Christmas Day and the production team worried people might not bother tuning in to watch. By making the episode irrelevant to the plot of the complete serial as a whole, they didn't have to worry about people tuning back in the week after and not having a clue what was going on. The BLAM aspect is further emphasized when one realizes that the character of Sara Kingdom, featured in the silly goings-on in the episode, killed her own brother only a couple of weeks earlier and is supposed to be working through the guilt related to this.
- Bizarro Episode: "The Feast of Steven". Our heroes have a chase through Hollywood in the 1920s, get arrested by police in the 1960s, and end up Breaking the Fourth Wall.
- Ensemble Dark Horse: Sara Kingdom, one of the best companions that never were.
- Hilarious in Hindsight: The Doctor is unfamiliar with cricket. Four incarnations later...
- They Wasted a Perfectly Good Character: Sara Kingdom, a badass space mercenary who killed her own brother in pursuit of her goals, then began questioning everything she'd ever learned when the Doctor's philosophy began to get to her. She even travels with the Doctor in the TARDIS for several months in a Time Skip between episodes. She gets killed off in a slightly Stupid Sacrifice at the end of the story. The production team actually were open to the idea of keeping her as an ongoing character, but Jean Marsh didn't want to commit to the series full-time.
- Values Dissonance: The Doctor makes a rather racist comment as a punchline to a comedy sequence that would absolutely never be allowed on the screen today:This place is a madhouse, it's all full of Arabs! Come on, let's go.
- Visual Effects of Awesome: The Daleks marching through the jungle with flamethrower torches in are utterly beautiful.
- What Do You Mean, It's for Kids?: At the time, Doctor Who was considered a series for kids. As such, the decision to kill off not one but two ongoing characters - one of whom earlier in the story is shown murdering her own brother - in an extremely complex (for its day) storyline that was three times longer than the average story, made this one of the more controversial stories of the Classic Era, an experiment that would never again be repeated, and it would be 18 years before another companion was killed off. The story ending with a planet-destroying weapon ageing the Doctor's (temporary) companion into a decomposed pile of dust also didn't do much to placate the Moral Guardians.
