SEX/NUDITY 2 - A 16-year-old girl wears a skimpy tank top throughout the film, which reveals cleavage and midriff along with short-shorts that reveal bare legs; in one scene, we see a close-up of her short-short covered bottom and bare thighs. A woman wears a low-cut dress that reveals cleavage. A man wears open-necked shirts that reveal parts of tattoos. A man wears tight T-shirts that cling to bulging pectoral muscles and reveals muscular arms with tattoos. A teenager changes shirts and we see his bare shoulders and back.
► A teen girl kisses a teen boy and then holds his hand.
► A man thrusts a lit flare into the face of a tall lizard that bites it off and the man says, "That's emasculating"; he also tells another man, "She may be interested in making you her husband," to which the other man replies, "No, it might be you she's interested in."
► A man teaches a teen boy to attract women by shimmying his pectoral muscles; the teen is embarrassed and refuses to copy the behavior.

VIOLENCE/GORE 5 - A helicopter containing five people runs into a hurricane and thundering storm and we see a huge black twister three times: the helicopter breaks apart and sends debris and parts flying toward the audience, there are lightning flashes several times with loud thunder, we see shattered glass and the skin of the copter peels off, but no one is injured; the copter falls through the eye of the hurricane, there are shouts and thunder, the screen goes black and we then see a sunny beach and all four people unharmed amid scattered helicopter parts.
► On an island, we see numerous huge lizards and giant insects. We see half a dozen large spiders and webs of different kinds. A man steps and falls into a large lizard egg, where he is encased in slime and finds a slim-covered baby lizard; the man runs when an adult lizard roars toward the audience with slimy mouth and teeth several times, chases four people and is knocked out by two logs swinging on vines. A huge red centipede slides across the screen in close-up and twice jumps head-on toward the audience and roars.
► Several scenes depict a volcano spewing small amounts of lava and one scene features an eruption where the volcano flies apart and chunks of rock and molten gold fly toward the audience. A tidal wave hits an island that begins to sink. An earthquake shakes rocks off cliffs, but no one is injured.
► A huge amount of bird droppings hit a man while he and three other people ride on the back of large bees and three huge, screaming birds attack them; two birds collide head-on into each other, send feathers flying toward the audience and the last bird flies and sticks into a spider web as the large spider crawls toward it and the scene ends.
► A teen girl crawls through a dark tunnel containing cobwebs, explores a mountain cave containing an old skeleton in a chair and a skull on the floor and climbs back out when an earthquake begins to shake the cave. People drive a sub away through a field of boulders and glowing lava from an exploded volcano and use a torpedo to break one up. Three people fall into the sea and a submarine opens a large door and scoops them up safely.
► A teenage boy rides his dirt bike through streets at night, chased by three police cruisers; he jumps a fence with the bike in 3D close-up, flies off, lands in a swimming pool unharmed and we later see the boy arguing with his stepfather.
► A fishmonger chops the head from a large fish in close-up with a huge cleaver and the head is thrown off screen. The pitchfork of a statue atop a pedestal pokes toward the audience. A launched harpoon speeds toward the audience at eye level.
► A teen boy falls, dislocates his ankle and two men pop it back in quickly before the boy can feel additional pain; they bandage the ankle and leg and the boy finds a stick for a cane.
► A man and a teen boy jump off a cliff into the sea in order to find an anchored submarine; in dark, underwater scenes around the sub, a giant electric eel sparks continually and swims toward the two people, gliding by in close-up, sparking at the audience and slamming itself into the sub several times.
► People harpoon a giant electric eel in order to jumpstart a submarine's engine.
