On January 28, 1998, the film was released on DVD by MGM Home Video. Its release from MGM contained 14 minutes of scenes that were cut from the film's North American release. In 2002, the film was restored with the 14 minutes of scenes cut for US release re-inserted into the film. Clint Eastwood and Eli Wallach were brought back in to dub their characters' lines more than 35 years after the film's original release. Voice actor Simon Prescott substituted for Lee Van Cleef, who had died in 1989, and other voice actors filled in for since deceased actors. In 2004, MGM released this version in a two-disc special edition DVD.
Disc 1 contains an audio commentary with film writer and critic Richard Schickel. Disc 2 contained two documentaries, "Leone's West" and "The Man Who Lost The Civil War", followed by the featurette "Restoring 'The Good, the Bad, and the Ugly'"; an animated gallery of missing sequences titled "The Socorro Sequence: A Reconstruction"; an extended Tuco torture scene; a featurette called "Il Maestro"; an audio featurette named "Il Maestro, Part 2"; a French trailer; and a poster gallery.
This DVD was generally well received, though some purists complained about the re-mixed stereo soundtrack with many completely new sound effects (notably, the gunshots were replaced), with no option for the original soundtrack. At least one scene that was re-inserted had been cut by Leone before the film's release in Italy but had been shown once at the Italian premiere. According to Richard Schickel, Leone willingly cut the scene for pacing reasons; thus, restoring it was contrary to the director's wishes. MGM re-released the 2004 DVD edition in their "Sergio Leone Anthology" box set in 2007. Also included were the two other "Dollars" films, and Duck, You Sucker!. On May 12, 2009, the extended version of the film was released on Blu-ray. It contains the same special features as the 2004 special edition DVD, except that it includes an added commentary by film historian Sir Christopher Frayling.
The film was re-released on Blu-ray in 2014 using a new 4K remaster, featuring improved picture quality and detail but a change of color timing, resulting in the film having a more yellow hue than on previous releases. It was re-released on Blu-ray and DVD by Kino Lorber Studio Classics on August 15, 2017, in a new 50th Anniversary release that featured an attempt to correct the yellow color timing from the earlier disc. Though some fans complained that their efforts actually worsened the look of the master. Despite their 2017 release claiming to have both the theatrical and extended cuts, it was in fact determined that their theatrical cut disc was flawed and not only was missing shots, but also had additional shots not intended to be in the theatrical cut. On April 27, 2021, Kino released an Ultra HD Blu-ray, this time containing the correct theatrical cut, once again using the same master from the 2014 Blu-ray, but with extensive and more proper color correction. However, due to being too costly, the extended version was dropped from this release but the extra scenes were included as a special feature.
In 2025, Arrow Video released all three Dollars movies in remastered 4K transfers in the United Kingdom. Using the same base scans that created the masters on Kino's releases, they were able to create entirely new masters featuring HDR grading and newly restored mono tracks. In addition to a new fully restored versions of the theatrical and extended cuts, they also created multiple variants of the extended cut, which you can either watch it with or without the "grotto" scene and with or without the uncut Tuco torture scene (restored from a 35 mm print). Also included is a version that integrates deleted close ups of Angel Eyes whenever he first arrives at Stevens' house and another deleted scene where Blondie finds bones in the desert whenever he's being tortured by Tuco. But despite Arrow being able to include the theatrical and multiple variants of the extended cut, they were not able to include the original Italian cut or the Italian dub due to rights issues with the Italian rights holders. However, they were able to include the Italian specific moments as supplemental features.
The following scenes were originally deleted by distributors from the British and American theatrical versions of the film but were restored after the release of the 2004 Special Edition DVD.
During his search for Bill Carson, Angel Eyes stumbles upon an embattled Confederate outpost after a massive artillery bombardment. Once there, after witnessing the wretched conditions of the survivors, he bribes a Confederate soldier (Víctor Israel, dubbed by Tom Wyner) for clues about Bill Carson.
After being betrayed by Blondie, surviving the desert on his way to civilization, and assembling a good revolver from the parts of worn-out guns being sold at a general store, Tuco meets with members of his gang in a distant cave, where he conspires with them to hunt and kill Blondie.
The sequence with Tuco and Blondie crossing the desert has been extended: Tuco mentally tortures a severely dehydrated Blondie by eating and bathing in front of him.
Tuco, transporting a dehydrated Blondie, finds a Confederate camp whose occupants tell him that Father Ramírez's monastery is nearby.
Tuco and Blondie discuss their plans when departing in a wagon from Father Ramírez's monastery.
A scene where Blondie and Angel Eyes are resting by a creek when a man appears and Blondie shoots him. Angel Eyes asks the rest of his men to come out of hiding. When the five men come out, Blondie counts them (including Angel Eyes), and concludes that six is the perfect number, implying one for each bullet in his gun.
The sequence with Tuco, Blondie, and Captain Clinton has been extended: Clinton asks for their names, which they are reluctant to give.
The footage below is all featured within supplementary features of the 2004 DVD release
Additional footage of the sequence where Tuco is tortured by Angel Eyes's henchman was discovered. The original negative of this footage was deemed too badly damaged to be used in the theatrical cut.
Lost footage of the missing Socorro Sequence where Tuco continues his search for Blondie in a Texican pueblo while Blondie is in a hotel room with a Mexican woman (Silvana Bacci) is reconstructed with photos and unfinished snippets from the French trailer. Also, in the documentary "Reconstructing The Good, the Bad, and the Ugly", what looks to be footage of Tuco lighting cannons before the Ecstasy of the Gold sequence appears briefly. None of these scenes or sequences appear in the 2004 re-release but are featured in the supplementary features.
