Since 2000 , Fedkiw has been a consultant with Industrial Light & Magic receiving screen credits for work on '' Terminator 3 : Rise of the Machines '' , '' Star Wars : Episode III – Revenge of the Sith '' and '' Poseidon '' . In addition , he has worked on all three Pirates of the Caribbean and some Harry Potter movies . Fedkiw 's techniques have made possible the renderings of the sea in the Pirates movies and the dragon 's flaming breath in '' Harry Potter and the Goblet of Fire '' . They have also made possible the rushing floodwaters in '' Evan Almighty '' and were first used with T-X in '' Terminator 3 '' . Fedkiw feels the best result of the use of his techniques was the sinking ship shots in '' Poseidon '' . '' Pirates of the Caribbean : Dead Man 's Chest '' won the Academy Award for Visual Effects at the 79th Academy Awards awarded on February 25 , 2007 and '' Poseidon '' was also nominated that year in that category . Among the applications that Fedkiw 's math engine is responsible for is the tentacles of Davy Jones ( pictured left ) in the Academy Award-winning '' Dead Man 's Chest ''
