''The Ruling Class'' is a 1972 British black comedy film, and adaptation of Peter Barnes' satirical stage play which tells the story of Jack, a paranoid schizophrenic British nobleman (played by Creator/PeterOToole) who inherits enormous power and privilege in Great Britain. His family (and neglected heirs) attempt to steer him into siring an heir which they can look after (along with the massive estate) while Jack, the 14th Earl of Gurney, is tucked back into a straightjacket. The biggest obstacle: He's convinced he's Jesus Christ.

The film co-stars Alastair Sim, William Mervyn, Coral Browne, Harry Andrews, Carolyn Seymour, James Villiers and Arthur Lowe. It was produced by Jules Buck and directed by Peter Medak. The film is a "commercial failure [...that] has since become a cult classic"; Peter O'Toole described it as "a comedy with tragic relief".

!!This film provides examples of:
----
* AllLovingHero: As long as he thinks he's Jesus Christ, the 14th Earl of Gurney gets along with everybody.
* ArmorPiercingQuestion: A psychiatrist asks the Earl one in the second half. The Earl replies with an Armor Piercing Statement, and seconds later, they're both singing an old college boating song.
* TheBadGuyWins: A very strange example, but he does.
* BeCarefulWhatYouWishFor: All the Gurneys want is for the 14th Earl to stop referring to himself as Christ, and start answering to his given name, Jack. [[spoiler: He does. As in, Jack the Ripper.]]
* BecomingTheMask: Grace is recruited to marry the 14th Earl and produce an heir that can take over the estate. She surprises herself when she genuinely falls in love with him.
* BerserkButton: The 14th Early of Gurney will FLIP OUT if you call him by his given name, Jack, or contest any of his reality, for that matter. Not played for laughs.
* BlackComedy: The Butler drunkenly discovers [[spoiler: Lady Claire]] dead on the floor. Instead of showing horror, he shouts and cheers for joy that there's one less Gurney in the world.
* BrainwashedAndCrazy: The Gurneys successfully break the 14th Earl of his delusion that he is the Christ. [[spoiler: He replaces the role with Jack the Ripper and lives up to the name.]]
* BreakingTheFourthWall: Lady Grace does a burlesque act for the audience, in her wedding dress. On her wedding night.
* BreakThemByTalking: The Earl of Gurney receives this from an equally mad Old Testament 'God', re-inforced by his psychiatrist.
* {{Burlesque}}: Lady Grace does one in her wedding dress. On her wedding night. To the FOURTH WALL.
* [[spoiler: TheButlerDidIt: Tucker is framed for this to keep Jack out of prison after he murders a lover.]]
* CloudCuckoolander: The 14th Earl of Gurney firmly believes he's Jesus Christ, and a loving god. Harmless as the trope implies [[spoiler: until he starts believing he's Jack the Ripper, instead]].
* DarkMessiah: Once he's 'cured', the 14th Earl gains political standing by calling for Old English Values, severe punishments, and decrying anything resembling modernity or change. "Bring back fear!!"
* EmpathicEnvironment: Thunderheads scream and lightning splits the sky... [[spoiler: the night the 14th Earl is broken of his Christ delusion, replaces it with Jack the Ripper, and his wife gives birth.]]
* EstablishingCharacterMoment: As Jesus Christ, he enters beneath a halo of sunlight and spouts messages of love and kindness. [[spoiler: As Jack the Ripper, he points a gun at his entire family and has a jarring verbal tic.]]
* AGodAmI: The 14th Earl of Gurney in spades. Shared with and contested by another delusional who believes he is the angry, Old Testament God.
* {{Hallucinations}}: The 14th Earl has a few, between seeing lightning coursing between the Old Testament God's fingers, a man in a gorilla suit, even transporting himself to Edwardian London.
* HellIsThatNoise: Try [[http://www.youtube.com/watch?v=9c3CwmLjVpE this]] on for size.

* [[spoiler: JackTheRipper: The delusion that replaces the 14th Earl's far more benevolent Christ role. He murders two women, including his wife.]]
* TheJeeves: Tucker is this at turns. The 13th Earl was decidedly eccentric and Tucker didn't bat an eye. The 14th is legitimately insane, and Tucker stays in service. He's rewarded 30,000 pounds for his troubles... [[spoiler: and later framed for murder when Jack decides he's Jack the Ripper.]]

* LieDetector: The 14th Earl is asked if he's God. He says no. The machine says he's lying.

* TheMentallyDisturbed: Charming as he can be, the 14th Earl is legitimately a danger to himself and others.
* MassiveMultiplayerScam: The 14th Earl of Gurney is convinced he's married to a woman who's been dead for years. His unscrupulous uncle brings him a Mole who plays along. The Earl immediately sees her as the genuine article.

* ReallyGetsAround: Lady Claire. Grace implies she is too, but happily settles down with Jack.

* UpperClassTwit: Dimmesdale. "Oh please help! I'm stuck in the brambles!"
