The T-Rex Attack
Spielberg sells a 20-foot predator almost entirely through sound — the silence, the tremor rippling a glass of water, the off-screen footfalls — long before the T-Rex ever fills the frame.
Watch for
- The famous tremor in the glass of water — sound and vibration announcing the T-Rex before we see it.
- The use of near-silence and low rumble to build dread between the big sounds.
- How layered roars, footfalls and rain make a part-puppet, part-CGI dinosaur feel physically, terrifyingly real.

CContention
Spielberg sells a creature that barely exists on set almost entirely through sound design.
OObservation
The T-Rex's approach is signalled by a low rumble and the rippling water in a glass long before it appears, then by layered roars and ground-shaking footfalls.
CConnotation
Letting sound arrive first makes the threat enormous and inevitable, and grounds a fantastical creature in convincing physical weight.
AAudience
We feel the dinosaur coming in our chest before we see it, which makes the reveal land and the danger feel real.
Your turn
- What tells us the T-Rex is coming before we see it? How does that build suspense?
- How does sound make a special-effects creature feel physically real and heavy?
- Find a moment of near-silence. What does the quiet do to the tension?
For teachers
A vivid, accessible lesson in sound design and how audio sells a visual effect — great for Year 9–10. Some peril, but generally classroom-friendly. Pairs with the Audio page.
