En este caso no se trata de una versión extendida, sino de una edición restaurada después de que el metraje original fuera recortado en varias ocasiones y para diferentes reestrenos.

Aquí podéis leer un resumen al respecto:

Theatrical run

The film premiered at the Odeon Leicester Square in London on 10 December 1962 (Royal Premiere) and was released in the United States on 16 December 1962.

The original release ran for about 222 minutes (plus overture, intermission, and exit music). A post-premiere memo (13 Dec. 1962) noted that the film was 24,987.5 ft (70 mm) and 19,990 ft (35 mm). With 90 ft of 35 mm film projected every minute, this corresponds to exactly 222.11 minutes.

In an email to Robert Morris, co-author of a book on Lawrence of Arabia, Richard May, VP Film Preservation at Warner Bros., noted that Gone With the Wind, never edited after its premiere, is 19,884 ft of 35 mm film (without leaders, overture, intermission, entr'acte or walkout music) corresponding to 220.93 min.

Thus, Lawrence of Arabia, slightly more than 1 minute longer than Gone With the Wind, is the longest movie ever to win a Best Picture Oscar.

In January 1963, Lawrence was released in a version edited by 20 minutes; when it was re-released in 1971, an even shorter cut of 187 minutes was presented. The first round of cuts was made at the direction and even insistence of David Lean, to assuage criticisms of the film's length and increase the number of showings per day; however, during the 1989 restoration, he would later pass blame for the cuts onto by-then-deceased producer Sam Spiegel. In addition, a 1966 print, used for initial television and video releases, accidentally altered a few scenes by reversing the image.

The film was screened out of competition at the 1989 Cannes Film Festival. and at the 2012 Karlovy Vary International Film Festival.

Restored director's cut

The current "restored version", undertaken by Robert A. Harris and Jim Painten (under the supervision of director David Lean), was released in 1989 with a 216-minute length (plus overture, intermission, and exit music).

Most of the cut scenes were dialogue sequences, particularly those involving General Allenby and his staff. Two whole scenes—Brighton's briefing of Allenby in Jerusalem before the Daraa scene and the British staff meeting in the field tent—were completely excised, and the former has still not been entirely restored. Much of the missing dialogue involves Lawrence's writing of poetry and verse, alluded to by Allenby in particular, saying "the last poetry general we had was Wellington". The opening of Act II, where Faisal is interviewed by Bentley, and the later scene, in Jerusalem where Allenby convinces Lawrence not to resign, existed in only fragmented form; they were restored to the 1989 re-release. Some of the more graphic shots of the Tafas massacre scene—the lengthy panning shot of the corpses in Tafas, and Lawrence shooting a surrendering Turkish soldier—were also restored. Most of the still-missing footage is of minimal import, supplementing existing scenes. One scene is an extended version of the Daraa rape sequence, which makes Lawrence's punishment in that scene more overt. Other scripted scenes exist, including a conversation between Auda and Lawrence immediately after the fall of Aqaba, a brief scene of Turkish officers noting the extent of Lawrence's campaign, and the battle of Petra (later reworked into the first train attack), but these scenes were probably not filmed. The actors still living at the time of the re-release dubbed their own dialogue, though Jack Hawkins's dialogue had to be dubbed by Charles Gray (who had already done Hawkins' voice for several films after the former developed throat cancer in the late 1960s). A full list of cuts can be found at the Internet Movie Database. Reasons for the cuts of various scenes can be found in Lean's notes to Sam Spiegel, Robert Bolt, and Anne V. Coates. The film runs 216 minutes in the most recent director's cut available on DVD.
