Chapter 8 · Practical Effects vs. CGI: A Real Technical History
Terminator 2: An Earlier, Real CGI Landmark
Terminator 2: Judgment Day's own T-1000 — brought to life by Industrial Light & Magic — is real, documented as the first use of a computer-generated main character in a blockbuster film. The scale of the real effort involved was genuinely enormous: rendering just 15 seconds of footage took up to ten days, and a team of up to 35 ILM artists worked on only five minutes of the T-1000's total screen time. The film was the most expensive ever made at the time, with production costs between $94–102 million, including a real $5 million spent on the T-1000 alone.
"I've Just Become Extinct"
Tracing the Shift Across This Course
Looking back across every film covered so far, the real transition from physical to digital effects wasn't sudden — it moved gradually, and unevenly, across roughly two decades.
| Film | Real Effects Approach |
|---|---|
| Metropolis (1927, Ch.1) | Real physical miniatures and set-based photographic tricks |
| 2001: A Space Odyssey (1968, Ch.3) | All 205 shots deliberately built in camera |
| Star Wars (1977, Ch.4) | A new company, ILM, founded specifically because no capable effects studio existed |
| Alien (1979, Ch.5) | Real animatronics and practical creature design (H.R. Giger) |
| The Terminator (1984, Ch.6) | A real, hand-built puppet plus stop-motion endoskeleton sequences |
| Terminator 2 (1991, this chapter) | A real, groundbreaking CGI main character — the first of its kind in a blockbuster |
| Jurassic Park (1993, this chapter) | A real, deliberate pivot from planned go-motion to primarily CGI dinosaurs |
| Independence Day (1996, Ch.7) | A real, deliberate return to practical miniatures over CGI, specifically to save cost |
| The Matrix (1999, Ch.7) | A newly invented hybrid — a real physical camera array producing a digital-feeling result |
Practical vs. CGI: Real Tradeoffs, Not a Simple Upgrade
Questions to Sit With
Independence Day deliberately used more practical miniatures than CGI in 1996, three years after Jurassic Park had already proven CGI creatures could look genuinely convincing. What do you think that choice says about how "obviously better" any new technology actually looks to the people deciding whether to use it?
Phil Tippett's own career didn't end when CGI replaced his original go-motion plan — his real skill was redirected into supervising the CGI animators instead. What do you think this says about which skills actually survive a genuine technological shift, and which don't?
Looking at the table above, do you think the real shift from practical to digital effects across this course's own nine films happened gradually, or do you see a genuine, sharp turning point at a specific film?
Quick Reference — Chapter 8
- Terminator 2 (1991) — the T-1000, ILM's real, groundbreaking first computer-generated main character in a blockbuster, at a real $5 million cost
- Jurassic Park (1993) — Phil Tippett's planned go-motion dinosaurs replaced by CGI after a real, documented ILM test convinced Spielberg, with Tippett's own real "I've just become extinct" quote
- Tippett wasn't made obsolete — he supervised roughly 50 dinosaur shots and won a real 1993 Academy Award for Best Visual Effects
- The real shift traced across this course's own nine films happened gradually and unevenly, not as one clean technological replacement
- Independence Day (1996) deliberately chose practical miniatures over CGI to save cost, three years after CGI's own real breakthrough
