In the US, the film has been widely available on home video since 1980 and was re-released several times on VHS. It was first released on DVD in the US on 29 June 1999.
In the UK, the film was eventually released by Warner Home Video on 13 November 2000 (on both VHS and DVD), individually and as part of The Stanley Kubrick Collection DVD set.[89] Due to negative comments from fans, Warner Bros re-released the film, its image digitally restored and its soundtrack remastered. A limited-edition collector's set with a soundtrack disc, film poster, booklet, and filmstrip followed, and was discontinued. In 2005, a British re-release, packaged as an "Iconic Film" in a limited-edition slipcase was published, identical to the remastered DVD set, except for different package cover art. In 2006, Warner Bros announced the September publication of a two-disc special edition featuring a Malcolm McDowell commentary, and the releases of other two-disc sets of Stanley Kubrick films. Several British retailers had set the release date as 6 November 2006. The release was delayed and re-announced for the 2007 Holiday Season.
An HD DVD, Blu-ray, and DVD version was re-released on 23 October 2007, alongside four other Kubrick classics, with 1080p video transfers and remixed Dolby TrueHD 5.1 (for HD DVD) and uncompressed 5.1 PCM (for Blu-ray) audio tracks.[90] Unlike the previous version, the DVD re-release edition is anamorphically enhanced. The Blu-ray was reissued for the 40th anniversary of the film's release, identical to the previously released Blu-ray, plus a Digibook and the Stanley Kubrick: A Life in Pictures documentary as a bonus feature.[90]
In 2021, a 4K restoration was completed with Kubrick's former assistant Leon Vitali working closely with Warner Bros.[91] It was released in the US on 21 September 2021 and 4 October 2021 in the UK.
