Casablanca was initially released on Betamax and VHS by Magnetic Video and later by CBS/Fox Video (as United Artists owned the distribution rights at the time). In 1989, the Criterion Collection released a Laserdisc release sourced from a nitrate print that includes supplements such as an audio commentary by Ronald Haver, a treatment for an unreleased sequel and wartime footage of the city of Casablanca.[146] Criterion would issue a CLV version of this in 1991 with only the film and commentary. It was next released on laserdisc in 1991, and on VHS in 1992—both from MGM/UA Home Entertainment (distributing for Turner Entertainment Co.), which at the time was distributed by Warner Home Video. It was first released on DVD in 1998 by MGM, containing the trailer and a making-of featurette (Warner Home Video reissued the DVD in 2000). A subsequent two-disc special edition, containing an audio commentary by Roger Ebert, documentaries, Carrotblanca and a newly remastered visual and audio presentation, was released in 2003.[147]
An HD DVD was released on November 14, 2006, containing the same special features as the 2003 DVD.[148] Reviewers were impressed with the new high-definition transfer of the film.[149]
A Blu-ray release with new special features came out on December 2, 2008; it is also available on DVD.[150] The Blu-ray was initially only released as an expensive gift set with a booklet, a luggage tag and other assorted gift-type items. It was eventually released as a stand-alone Blu-ray in September 2009. On March 27, 2012, Warner released a new 70th Anniversary Ultimate Collector's Edition Blu-ray/DVD combo set. It includes a brand-new 4K restoration and new bonus material.[151][152] This 4K restoration was completed at Warner Bros. Digital Imaging from a nitrate print, because the original negative no longer exists.[153]
The film was also released on Ultra HD Blu-ray in November 8, 2022.
