Though nearly 35 years of “Star Wars” fandom have yielded all kinds of memorabilia inspired by George Lucas’s outer-space epic, including light saber look-alikes and wearable reproductions of Princess Leia’s slave costume, one holy grail has lately eluded fans: a video version of the “Star Wars” films that takes the fullest advantage of their top-of-the-line home theater systems.

That’s a Death Star-size void that Lucasfilm plans to fill shortly. On Saturday, the studio announced that it will release all six live-action “Star Wars” features on Blu-ray DVD in fall 2011. A boxed set containing the Blu-ray versions of the movies, from 1977’s “Star Wars” through the final 2005 prequel, “Star Wars: Episode III — Revenge of the Sith,” will mark the first time the films have been offered in a high-definition home format, and will include documentary features and previously unseen footage.

Given Mr. Lucas’s exacting standards for film presentations (he founded the company THX) and Lucasfilm’s embrace of digital movie technology (digital projection was used for the theatrical release of all three “Star Wars” prequels, and the last two prequels were shot digitally), many fans expected that high-definition versions of the “Star Wars” features would soon follow.

But in a telephone interview, Mr. Lucas said he had been waiting to see if the Blu-ray format would be widely accepted by home viewers.
