Special Effects in Cinema Trivia Questions

Three mechanical sharks were built, but they constantly broke down due to saltwater corrosion. The delays forced Spielberg to shoot around the shark, making the film scarier by hiding it.

Hitchcock bought real skeletons from a medical supplier because they were cheaper than plastic replicas. The skull appears briefly when the knife hits the shower wall.

James Cameron built a massive 17-million-gallon tank at Rosarito Beach, Mexico. The sinking used real water, miniatures, and some CGI augmentation for crowds and distant shots.

Director of photography John Gaeta rigged 120 Nikon cameras in a circle and triggered them in sequence to create the iconic slow-motion spin. CGI only cleaned up the frames.

Forced perspective made hobbits look small, but dwarves were played by actors of normal height. The trick placed taller actors farther away, not on stilts—stilts would have ruined the camera angle.

While ILM used many matte paintings, the flames in Star Wars were mostly miniature explosions or animation, not painted glass. This myth likely confuses them with the painted laser blasts.

Lightsabers were actually three-sided rods covered in reflective tape, spun by a motor to create a blurry glow. The color was added later by rotoscoping each frame by hand.

Bolaji Badejo, a 7'2" Nigerian design student, was cast for his lanky frame. He wore a latex suit and performed the creature's movements on set, with only the head built as a puppet for close-ups.
