Terminator 2: Judgment Day won four Academy Awards. At the 64th Academy Awards, the film was recognized for technical achievements that helped redefine blockbuster visual effects in the early 1990s.
Its wins were Best Makeup, Best Sound, Best Sound Effects Editing, and Best Visual Effects. The visual-effects award honored work by Industrial Light & Magic and the film's effects team, including groundbreaking computer-generated imagery used for the liquid-metal T-1000.
The film also received nominations for Best Cinematography and Best Film Editing, but it did not win either category. That distinction explains why some lists show six Oscar nominations while the correct number of wins remains four.
Released in 1991, Terminator 2 became the year's highest-grossing film worldwide and was praised for combining practical stunts, animatronic effects, miniature work, and digital techniques. It is often credited with helping move mainstream filmmaking toward computer-generated effects.
