Fred, Daphne, Velma, Shaggy and Scooby soon realize that they cannot solve this mystery without help from each other. The film is a combination of live action and computer animation. With Sarah Michelle Gellar, Freddie Prinze Jr., Matthew Lillard, Linda Cardellini and Rowan Atkinson. [1:26]

SEX/NUDITY 3 - A young man and woman kiss romantically. We see young men and women dancing and swimming together at a poolside party. Teen girls swoon over a young man. The young women wear outfits (hip-huggers, mini-skirts, crochet tops, bikinis, etc.) that reveal cleavage, bare abdomens, bare backs, and bare thighs. A young woman screams: "I have a wedgie," a young man says, "even dorky girls turn me on," and a young man talks to a dog about "cleaning his beans." When a young man's "protoplasm" enters a young woman's body he says, "I can look at myself naked" and we see her stroking her clothed breasts. There is a reference to a jilted lover.

VIOLENCE/GORE 4 - There are creepy looking monsters who have the head of a dog with big fangs and horns, and tall skeletal bodies with long pointed claws; they blow a green fog in people's faces that knocks them unconscious. Also, Spooky Island is inhabited by people wearing skeleton masks, their faces are painted and their bodies are covered with tattoos. A small dog grows into a monstrous creature with fangs and a booming voice, and chases and threatens another dog. Monsters chase and grab a young man and woman (we see them being dragged by the feet while unconscious), they chase and try to catch others (they break through floors, windows and roofs). A machine (called "The Pincers") opens a hole in a dog's chest and pulls out a "protoplasmic" head leaving the dog's body limp and presumably dead. A man's mask is taken off and it reveals a robot with a small dog inside. A monster-dog's chest is opened by the pincers and he shrinks back to normal size. A haunted castle becomes animated with armored suits moving and swinging bladed weapons, food flies off a table, covers a man and dog up and pins them to a wall while fanged jaws snap at them, and blades swing toward two people as they run away and one of them is hit and tossed through a glass window. A roller coaster car runs into a young woman, who clings to it and stops just short of several swords pointed toward her. We see a large pool of "protoplasmic" heads floating around; as the heads are plucked out, they seek their bodies and when they find them they slam into them knocking them to the ground and a monster pops out; the monster then disintegrates when exposed to sunlight. A "protoplasmic" head flies around a cave knocking people down as it bounces around. A dog goes into dark woods alone and he is confronted by a monster who slashes and growls at him and chases him up a tree. A young woman fights a man with lots of kicking, punching, twirling, flipping and the man ends up hanging over an opening in the ground through which he falls and knocks over a cauldron of "protoplasmic" heads. A young man punches and elbows a man in the face and kicks him in the groin. A young woman hits her head on a branch while riding a 4-wheeler and her eyes and face become distorted; she stretches her skin and it goes back to normal. A group of young men chase another young man and a dog; they hide in a shack and the young men on the outside punch out the windows, and jump on the roof trying to get at them. A young woman grabs a young man and a dog by their respective throats and breathes green fog in their faces. A young man and a dog skateboard along a conveyor belt and through many hazards (swinging blades, stamping arms, etc.) and end up crashing into a pile of toys. They also race on 4-wheelers while being chased by growling, snarling young men, they hide in a barrel and a ghost blows a flame at them which ignites the dog's tail (we see it smoldering), they eat hot chili peppers and react with anguish (they gasp, guzzle beverages and smoke comes out of their ears), and they have an extended flatulating and burping contest. A dog falls down a hole in the ground and a young man jumps in after him (he lands hard on the ground at the bottom), and a dog is slammed into a windshield when the car he is riding in stops short. A dog hits another dog who slams into a rock wall, a dog punches a young man in the nose, a dog kicks a young man in the face, a dog growls, barks at and lunges at a cat (we hear someone say "...don't eat the cat"), a dog barks at a young man, a dog barks at a young woman, a dog and a young man argue and swing at each other, a man swats a dog, and a young man flicks a dog on the nose. A huge monster-dog sneezes green slime on another dog. A young man and woman swing out of control from tethers high off the ground and they slam into rock walls and one slams into a man knocking him to the ground, and a young woman falls over a railing and dangles from a chain wrapped around her ankle. A ghost flies through the air while holding a screaming young woman under its arm. A young woman picks a young man up and throws him through the air, a man picks up a young man and throws him onto the ground. In one scene, a fresco on a wall has eyes that follow people as they move. A man performs a voodoo ritual and draws a knife up over a dead chicken hanging from the ceiling (he says he's going to perform a sacrifice). A man holds a dead "arnuky beast" (looks like a shrunken head with a body) and performs another voodoo ritual. A young woman grabs a young man around the throat, a young woman is nearly trapped in a pyramid, and a young man nearly hits a young woman. There are several verbal threats. A young woman eats Scooby-snacks. A dog urinates on a young woman. There are a couple of scenes where people are startled by someone coming into a room unexpectedly.

SUBSTANCE USE - There are possible references to smoking marijuana: There's a young woman whose name is "Mary Jane," which is apparently a slang term for marijuana, and Shaggy exclaims that it is his favorite name; and we see smoke coming out of Shaggy's van, which, however, is revealed to be from grilling.

DISCUSSION TOPICS - 1970's TV shows, greed, taking credit for other people's work, realizing your worst fears, revenge, the supernatural realm, voodoo, brainwashing, best friends, cults, ancient rituals, trust, corruption, power.

MESSAGE - Friends don't give up on friends.

(Note: For parents and children familiar with the original Scooby-Doo TV series, this film has little to do with it. Its tone is darker and the characters -- except Shaggy and Scooby -- have been reinvented and made contemporary. Also, please keep in mind that children who care for the characters may be upset when it is revealed that one of them is not very nice.)
