Two films; there are tropes for both on this page. Robin Hardy's original film was made in 1973 with Christopher Lee as Lord Summerisle. It's a sort of suspense/horror/folk musical. Neil LaBute remade it in 2006 with Nicolas Cage.To sum it up it in the nicest terms possible: The original is generally considered to be an influential Cult Classic within the horror film genre, and the remake is mostly viewed as inferior, and is probably better remembered for its moments of unintentionalfunniness than for being scary.In 2011 Robin Hardy released The Wicker Tree, a companion piece of sorts based on his novel 'Cowboys for Christ', with Lee appearing in a cameo (but not, as some have reported, as Lord Summerisle).
The original film provides examples of:
Affably Evil: Lord Summerisle. Possibly subverted. It's never clear whether Summerisle believes the religion of his island, or is just playing along to keep his subjects in line. If the former, he may genuinely believe the sacrifice is necessary for the harvest.
And he tries to soothe his intended sacrifice:
Howie: I am a Christian. And as a Christian I hope for resurrection. And even as if you kill me now, It is I who will live again, not your damned apples! [The Villagers prepare him for sacrifice] No matter what you do, you can't change the fact that I believe in Life Eternal, as promised to us by our Lord Jesus Christ. I BELIEVE IN THE LIFE ETERNAL AS PROMISED BY OUR LORD JESUS CHRIST!
Lord Summerisle: That is good. For believing what you do, we confer on you a rare gift these days: A martyr's death. You will not only have life eternal, but you will sit with the saints among the elect. Come, it is time to keep your appointment with the Wicker Man.
The Bad Guy Wins: Though thanks to Howie's final speech, only till the apple harvest fails again. If you look at it that way, (see Taking You with Me further down) you could arguably say that Howie was the real winner.
Bawdy Song: The customers at a pub engage in a lusty rendition of "The Landlord's Daughter", to the annoyance of the straightlaced protagonist and the amusement of Willow, the Really Gets Around daughter of the pub's landlord. As Christopher Lee said in the DVD Commentary, it's a good song for when you've got a pint in your hand.
Genius Bonus: "The Landlord's Daughter" and "Willow's Song" are both based on actual ditties - the latter a compilation of two - that are Older Than Dirt. In fact, the latter is considered one of the oldest recorded songs in the world.
But I Would Really Enjoy It: Howie doesn't believe in sex before marriage, and is therefore still a virgin in middle age. Willow does her best to seduce him and fails, though Howie is literally trembling with desire.
Daylight Horror: Many of the events in the movie take place during the day, with the climax happening at dusk. It lets the audience admire the Scenery Porn and also makes the bizarre behavior of the townspeople even more unsettling.
Dark Reprise: Howie's reprise of the 23rd Psalm as counterpoint to the townsfolk's "Sumer is Icumen In" at the film's climax.
Enthralling Siren: A case of Maybe Magic, Maybe Mundane when Willow dances naked in the room next to Howie's, slapping the wall between them and singing to him. The staunchly Christian Howie is literally trembling with desire, but doesn't succumb.
Executive Meddling: Yes. British Lion execs stated it was the worst film they'd ever seen, edited the film and released it with no advertising. Fortunately, Roger Corman saved an unedited copy.
Face Death with Dignity: Rather hammily averted at first by Howie ("OH MY GOOOOOD!") but once the fire is actually lit, played straight, as Howie accepts his death and prays for his soul to go to Heaven.
Don't get too excited, since the butt shots are a body double. (To Ekland's disgust, people are forever asking her to autograph stills of that one particular scene. She has to patiently explain to them that it isn't actually her.)
For the Evulz: The only possible explanation for Daisy's beetle-abuse.
That, or it's a symbol of Howie's fate: the closer he gets to the answer of where Rowan is (i.e. the more he goes around the nail), the more entangled he is and the more difficult it is for him to escape
Gambit Roulette: Summerisle's plan to trick Sgt. Howie into coming to the island of his own free will and stay until May Day so they can sacrifice him. There's a lot of chance in this plan and a lot can go wrong.
Genre-Busting: Is it a crime movie? A horror movie? A mystery? A fantasy movie? You can even argue that it's a Musical, if you're so inclined... or an excuse (albeit a good one) for Fanservice.
Grey and Gray Morality: Howie, whatever you think of his blustery self-righteousness, is genuinely trying to be a good police officer and save a child's life. The villagers with the possible exception of Lord Summerisle, however creeped out you may be by their practices, genuinely believe that they are saving their harvest.
Holier Than Thou / Real Men Love Jesus: Sgt. Howie's behaviour is, depending on interpretation, either that of a sanctimonious prude, that of a deeply honourable and upright officer motivated by his faith or both.
"I Want" Song: Most of the songs, except the hero's song, which is the 23rd Psalm, starting "The Lord is my shepherd, I shall not want."
Jerkass: Lord Summerisle, the island inhabitants, and some of Howie's co-workers from the original version's beginning. Despite his affability, Lord Summerisle probably reigns supreme in this category; as the co-workers are minor, the inhabitants genuinely devout, and Howie at least genuinely wants to do the right thing. Summerisle has no real excuse.
A Man Is Not a Virgin: Subverted (in the original, but not the remake), using the audiences' expectations against them.
Oh Crap: This is one of the few films where the main character can shout "Oh Jesus Christ!" and have it come across as a true, in-character Oh Crap moment.
Christopher Lee has a nicely subtle one when Howie points out that if his own death doesn't help the next harvest, the villagers will likely conclude that only Summerisle himself will be a large enough sacrifice to satisfy their gods.
Stout Strength: Oak. Howie may look more fit, but he doesn't have a chance. The rest of the crowd can just stand around and watch. Hinted at early on in the inn, when we see Oak carrying a grown man around on his shoulders for fun.
Taking You with Me: Howie points out that if his sacrifice doesn't bring back the crops, only Lord Summerisle will be a suitable sacrifice next year. Summerisle's reaction shows that it briefly hits home before he declares that the crops won't fail; even if he doesn't believe in the island's gods, the rest of the island certainly does!
Theme Naming: All the townsfolk are named for trees or plants. May Morrison, gets a doubly symbolic name, with May not only being a plant (another name for hawthorn), but also a month of fertility. And when an islander dies, they plant the tree the deceased was named after on the grave, to symbolize that death is part of the cycle of life.
Values Dissonance: In-universe, with Howie being baffled or horrified at the islanders' pagan beliefs and the islanders being equally baffled by his Christian morality.
Gambit Roulette: The islander's plan would have fallen apart before it started, if Edward hadn't been knocked unconscious while trying to save the two women in the burning car, allowing them to escape unseen. The Plan only becomes more dependent on luck from that point on, considering how much of it required him to notice the right thing or even be facing the right direction at the right time.
Gender Flip: Lord Summerisle was rewritten as Sister Summerisle
A Man Is Not a Virgin: Played straight: the virgin aspect was removed due to LaBute considering the notion of Cage playing a virgin ridiculous. They gave his character an allergy to bees instead. Not quite the same.
Meaningful Name: The protagonist Edward Malus, a lawman who spends the movie investigating a pagan cult, may be named for the Malleus Malificarum, a treatise on prosecuting witches published in the 15th century.
Alternatively, Malus is the Latin word for apple, and is used in the taxonomy of the species.
Milkman Conspiracy: Malus arrives to the island and comes to head with a terrifying paganist cult of...beekeepers?
My God, You Are Serious: Christopher Lee, who played Lord Sumerisle in the original, got this reaction when he mentioned the remake at a press conference.
Stupid Evil: The cult comes off as this, in stark contrast to the original film.
Too Dumb to Live: Edward, Cage's character - he barges onto the island and tries to throw his police weight around, with no plan, no actual authority enforce the non-existent plan and no backup. Not even a token visit to the local police to explain why he's there.
Again, allergic to bees, yet goes to an island famous for...bee keeping.
