Psycho needed blood to look dark as it swirled down a black-and-white drain. What did Hitchcock use?
- Stage blood
- Red ink
- Tomato soup

- A full-grown lion
- A baby elephant
- An elephant seal
- A bald eagle

Gandalf and Frodo share a shot, yet one looks twice as tall. How was that illusion often made?
- Gandalf wore weighted platform boots
- The lens stretched only half the frame
- Actors stood at forced-perspective distances
- Frodo performed inside a glass box
Show the answer, explanation, and sources
Answer: Actors stood at forced-perspective distances. Forced perspective created the apparent height difference in camera.
Placing actors at carefully different distances made equal-height performers look radically different. Moving platforms could preserve the illusion as the camera moved.

How was the rotating hallway fight in Inception filmed?
- Actors performed underwater
- The camera image was flipped in editing
- Wires pulled actors around a fixed set
- The entire hallway set rotated 360 degrees
Show the answer, explanation, and sources
Answer: The entire hallway set rotated 360 degrees. The production rotated a 100-foot hallway set around the actors.
A 100-foot corridor rotated around the actors while a camera moved with or beside it. The performers' real falls and changes in footing created the apparent shifts in gravity.

Why was the mechanical shark in Jaws called “Bruce”?
- It was named after Spielberg's lawyer
- It honored a shark researcher
- It reused the stunt diver's nickname
- It matched the prop builder's middle name
Show the answer, explanation, and sources
Answer: It was named after Spielberg's lawyer. The shark was named after Spielberg's lawyer, Bruce Ramer.
The 25-foot mechanical shark took the name of attorney Bruce Ramer. Repeated saltwater failures led Spielberg to suggest the shark's presence without showing it directly.

In The Wizard of Oz, which suspended material created the tornado effect across the miniature farm?
- A spinning glass tube filled with smoke
- A 35-foot muslin funnel like a windsock
- A painted rope dragged through sand
- A column of cotton wrapped around a fan
Show the answer, explanation, and sources
Answer: A 35-foot muslin funnel like a windsock. The tornado was created with a large muslin windsock.
The funnel hung from a moving overhead gantry while its base followed a slot below. Dust leaking through the fabric softened its edges into a storm.

Mary Poppins used a glowing yellow backing. Why was sodium-vapor light especially useful?
- Yellow made every costume look warmer
- Color film could not record blue indoors
- Its narrow wavelength made a precise separate matte
- Animators planned to paint every sky gold
Show the answer, explanation, and sources
Answer: Its narrow wavelength made a precise separate matte. A narrow yellow wavelength enabled precise image mattes.
A special prism split sodium-yellow light onto separate film while recording actors in normal color. Fine edges, motion blur, and transparent objects survived the composite.

10 · Challenge
Neo bends around bullets as the viewpoint sweeps past him. How did the original “bullet time” rig do it?
- One ultra-fast camera circled on a rail
- A rotating mirror filmed a motionless actor
- A computer invented every view from one photo
- An array of still cameras fired in sequence
Show the answer, explanation, and sources
Answer: An array of still cameras fired in sequence. The original bullet-time rig used approximately 120 still cameras in sequence.
Cameras arranged along a curve captured adjacent viewpoints in sequence. Interpolated frames joined the photographs into a continuous moving viewpoint around slowed action.
