* GeniusBonus: The various performances are even more hilariously appropriate if one knows the plays in question.
* HilariousInHindsight: Lionheart manipulates a critic into murdering his wife. He also kills his future wife in this.
* MagnificentBastard: [[ThemeSerialKiller Edward Lionheart]], driven to near-suicide by a group of [[StrawCritic callous theatre critics]], plots a gruesome revenge. Surfacing years later, Lionheart begins dispatching his enemies in ways inspired by the plays of Creator/WilliamShakespeare, while manipulating the others to proceed exactly how he wants them for best access and give himself more fame in the process of his vengeance. Lionheart manipulates one into murder to send him to prison, using [[CrazyHomelessPerson a group of derelicts]] to murder another and constantly runs rings around law enforcement and his enemies, all while remaining as [[LargeHam charismatic and larger than life]] as ever.
* {{Narm}}: Edwina [[spoiler:being killed, or at least knocked out cold, by being lightly tapped on the head with the award. Was that really the best shot they could come up with?]] [[note]] At least the stage play tries to fix this by having her accidentally stabbed to death just as she was about to kill Devlin.[[/note]]
* RetroactiveRecognition: Mrs. Sprout is played by Creator/JoanHickson, who would later be best known for playing Literature/MissMarple in [[Series/MissMarple1984 the 1980s series]].
* SpiritualAdaptation:
** ''Film/TheAbominableDrPhibes'' and ''Theatre of Blood'' both have Creator/VincentPrice playing the hammy ThemeSerialKiller VillainProtagonist and delivering [[PoeticSerialKiller poetic kills]] on a given group of people (who all have the same profession) for {{revenge}}.
** The plot wouldn't be out of place at all in ''Series/{{The Avengers|1960s}}''. Speaking of which, it also starred Creator/DianaRigg and Creator/IanHendry.
* ValuesDissonance: Some of the gay jokes are a little awkward today.
