* AlternativeCharacterInterpretation: Claudius' behavior in the last act of the books. Was he only feigning indifference, as the StoppedCaring entry suggests, or was he passive-aggressively grooming Nero as revenge for his generally miserable life?
* SugarWiki/AwesomeMusic / EarWorm: [[http://www.youtube.com/watch?v=pKwaCTfa1EE The main theme]].
* FanNickname: ''I, Clavdivs'' (achieved by pronouncing the Roman U's as V's; later home-video reissues do away with the Roman styling).
* SugarWiki/HeReallyCanAct: The series is proof that Brian Blessed is occasionally capable of understated acting. Between this and not having a beard, he's almost unrecognizable to people who know his later work.
* HilariousInHindsight: The joke Tiberius and his brother make about Livia, "They say a snake bit her once and died." Commonly known nowadays as one of the most well-known ChuckNorrisFacts.
** Livia, in her final moments, becomes a figure of pity when Caligula tells her he will not redeem her of all the blood on her hands by making her a goddess as he promised.
** As much as an asshole as Tiberius is, it's kind of hard not to pity him when he learns that his son had been murdered by his allegedly "trustworthy" advisor. Also he never really wanted to be emperor in the first place and was pushed into it by his mother... whose plans necessitated forcing him to divorce the woman he was deeply in love with.
** Caligula, murderous bastard that he is, is clearly suffering and terrified when he suffers his mental breakdown. Even later, he tells Claudius about how he barely sleeps at night, and seems almost aware that something about him is terribly wrong.
* MagnificentBitch: Livia. Four words: "Don't touch the figs."
** Livilla crosses it when she attempts to [[spoiler:poison her own daughter]] out of jealousy over Sejanus.
** Messalina crosses this when her schemes drive Appius Silanus to his death.
** Macro crosses the horizon in a big way after usurping Sejanus's power, as he then conducts a bloody purge on all of Sejanus's loved ones and supporters, massacring many in the street and personally seeing that Sejanus's daughter is raped and then killed.
* SpecialEffectFailure: A few examples, this being a lower budget television production from 1976. However, the writing and acting are so magnificent that this sort of thing doesn't matter.
** The assassination of Caligula shows how theatre actors stab someone and make it look real. Unfortunately, this is television, so their methods (squeezing a sponge soaked in red dye, sliding a sword down someone's back instead of into their chest, etc) are a bit too obvious. For that matter, this applies to most of the murders.
** As Marcellus prepares to address the (unseen) crowd at the games in the first episode, they fall silent to listen to him. When he says, "Let the games begin!" the applause begins - instantly at full volume, with not even the briefest crescendo. It's very clear that someone has pressed "play" on a tape left in the middle of an applause track.
** Caligula. Incest. Eating babies. Groping his great-grandmother. As she herself puts it: ''"Little Monster."''
** Agrippinilla addressing Claudius as "Uncle" in the middle of an attempt to seduce him with a passionate speech. Possibly intentional on her part, as she and Pallas have been musing that Claudius might be attracted to her precisely because of the incest factor.
* TearJerker: The death of Livia manages to become this.
** Herod's last words, written to Claudius:
--->'''Herod:''' ''"Marmoset, I am dying. My body is full of maggots. Forgive me. Forgive your old friend, who loved you dearly, yet secretly plotted to take the East away from you. I have failed. I played too dangerous a game. Little marmoset, you are a fool, but I envy you your folly. Do not weep for me; my punishment is just. I offended against the only living God. Farewell, my friend, whom I love more truly than you suppose. Farewell, little marmoset, my schoolfellow, and trust no-one. No-one. Your dying friend, Herod Agrippa."''
** From the same episode as the above, Calpurnia, Pallas and Narcissus having to tell Claudius of Messalina's adulteries. The denial, and then the heartbreak, on Claudius's face has to be seen.
* ValuesDissonance: Antonia, although her actress stated that her behavior is largely due to the time period in which she was raised.
* VisualEffectsOfAwesome: The makeup used to age Derek Jacobi, which is even more impressive now that we know he aged to look ''exactly'' like it.
* TheWoobie: Creator/DerekJacobi's portrayal of Claudius clinches it. While he's certainly not a saint, the amount of suffering he experiences over his lifetime makes it impossible not to feel sorry for him, especially since his only major character flaw is cowardice, which could easily also be interpreted as a sensible regard for his own skin. Even becoming Emperor, and then a God during his lifetime (which was not unprecedented but still unusual), isn't enough to turn his fortunes around. Indeed the scene in which he finds out he has become a God is also the scene in which he founds out that, [[DrowningMySorrows while drunk the night before]], he had signed the order to execute his (beloved, but also seriously treacherous and ''epically'' unfaithful) wife, and that she had just been killed. The fact that there is a historical basis to believe that the majority of the things that happen to him during the show actually happened puts the icing on the cake OF SUFFERING.
