John Knoll (born October 6, 1962) is an American visual effects supervisor and chief creative officer (CCO) at Industrial Light & Magic (ILM).

Along with Hal Hickel, Charles Gibson and Allen Hall, Knoll and the trio's work on Pirates of the Caribbean: Dead Man's Chest earned them the Academy Award for Best Visual Effects.

[2] Knoll has been praised by directors James Cameron, Gore Verbinski, Guillermo del Toro, and Brad Bird.

Del Toro, who worked with Knoll for the first time on Pacific Rim, stated "He basically has the heart of a kid and the mind of a scientist, and that's a great combination.

George never constricted his thinking to what he knew for sure the tools were capable of; his attitude was, "Yeah, well, I'm writing what I want to see, so you guys will figure it out."
