George Lucas has allegedly tinkered with the forthcoming 'Star Wars' Blu-Rays, which has angered fans.

The creator of the sci-fi franchise has reportedly added dialogue spoken by Darth Vader in 'Return of the Jedi' including a last minute "Nooo!" he shouts, as well as altering a Ben Kenobi noise in 'A New Hope', SlashFilm.com reports.

This has led to criticism from fans of the movies claiming the 67-year-old film producer's "tinkering" has "destroyed the dramatic impact of the most iconic scenes in American film history".

The nine-disc box set - which is set to drop on September 16 - includes all six of the films: 'Star Wars: Episode I The Phantom Menace', 'Star Wars: Episode II Attack of the Clones', 'Star Wars: Episode III Revenge of the Sith', and 'Star Wars: The Original Trilogy (Episodes IV - VI)'.

George previously made alterations to the 1997 'Star Wars: Special Edition', adding new scenes and special effects.
