Approximately 30 minutes of the film's 90-minute duration is made up of documentary footage.
Bugs Bunny: Superstar was the first of a series of Warner cartoon compilation movies released in the 1970s and 1980s. However, as a documentary, it does not fit the mold of the totally animated Warner Brothers compilation movies that began with 1979's The Bugs Bunny/Road Runner Movie. Bugs Bunny: Superstar was not considered a "canon" compilation movie because it was produced by Larry Jackson's Hare-Raising Films, rather than by Warner Bros. (1982's Bugs Bunny's 3rd Movie: 1001 Rabbit Tales is actually the fourth Bugs film, if Bugs Bunny: Superstar were to be included.)
The nine full-length cartoons featured in Bugs Bunny: Superstar were originally released between July 1940 and April 1948. In 1956, Associated Artists Productions ("a.a.p.") acquired the distribution rights to Warners' pre-August 1948 color cartoons. United Artists acquired a.a.p. in 1958 and thereby gained the rights to the aforementioned Warners cartoons; this is why United Artists distributed Bugs Bunny: Superstar and why Warners' compilation films of the 1970s and 1980s did not feature any pre-1948 cartoons. (Warners eventually re-acquired the rights to its pre-August 1948 cartoons after the 1996 Time Warner-Turner merger). Larry Jackson sought, unsuccessfully, to feature post-1948 Warners cartoons in his film.
Jackson had cultivated a friendship with Orson Welles and originally intended the bridging material of Bugs Bunny: Superstar to be a parody of Welles' Citizen Kane (1941). Welles' reluctance towards that idea ensured that Jackson's film would be a straightforward documentary; however, Welles did agree to provide narration for the film. Unfortunately, the audio quality of Welles' narration was muffled, which did not escape the notice of critics. Writing for The New York Times, Vincent Canby remarked that "Orson Welles bridges the gaps with facetious narration that sounds as if it had been left on someone's Phone-Mate." Larry Jackson later revealed he was unaware that Welles had recorded his lines in stereo. Only one track of Welles' recording - from the microphone that was furthest away - was used in the film's final mix, accounting for the relatively poor audio quality of the narration.
Upon its theatrical release, Bugs Bunny: Superstar was marketed with the tagline, "You won't believe how much you missed as a kid!" According to Larry Jackson, this was a reference to how audiences accustomed to watching Warner Brothers cartoons on television were unaware of the history behind those cartoons. Jackson commented that Bugs Bunny: Superstar outgrossed The Rocky Horror Picture Show during its original run. Jackson also recounts being personally complimented by Paul Simon, who was a fan of the film.
Contemporary critics pointed out that Bob Clampett's important role as one of the primary developers of the early Warner cartoons was noticeably slanted due to his prominent presence in Bugs Bunny: Superstar. In an audio commentary recorded for the 2012 DVD release, Larry Jackson claimed that in order to secure Clampett's participation and access to Clampett's collection of Warners history (memorabilia, drawings, films, photographs etc.), he had to sign a contract that stipulated Clampett would host the documentary, select the cartoons featured, and have approval over the final cut. Jackson further claimed that Clampett was very reluctant to speak about the other directors and their contributions. According to Jackson, Clampett was "insecure" about his place in the legacy of Warner Brothers cartoons. Furthermore, several of the cartoons featured in Bugs Bunny: Superstar are the "Blue Ribbon" versions which lack opening titles (including director credits). However, the three Clampett-directed cartoons are the original versions, preserving Clampett's director credit.
The documentary infuriated many of the Warner Brothers artists, as Clampett liberally took credit for several iconic Warner characters. Clampett implied that he was the creator of Bugs Bunny, claiming that he used Clark Gable's carrot-eating scene in It Happened One Night as inspiration for the character. (Although he never made the claim in Bugs Bunny: Superstar itself, Clampett further took credit for drawing the model sheet for the first Porky Pig cartoon I Haven't Got a Hat (1935), even though it was actually drawn by Friz Freleng.) Subsequently, Chuck Jones, who already had a strong dislike for Clampett, pointedly left out Clampett's name in the 1979 compilation film The Bugs Bunny/Road Runner Movie when Bugs discusses his "fathers" (i.e. Jones and other Warner's directors), and similarly omitted any mention of Clampett in his 1989 autobiography Chuck Amuck. Although Chuck Jones opted to not contribute to Bugs Bunny: Superstar, Larry Jackson claimed he remained friends with Chuck Jones for many years.
The release of Bugs Bunny: Superstar, in fact, brought to a head resentments that had grown between Chuck Jones and Bob Clampett for years. In June 1969, animation historian Michael Barrier interviewed Clampett for an article that appeared in issue #12 of Funnyworld magazine (fall 1970). In the course of the interview, Clampett implied or outright claimed to be the creator of characters such as Bugs Bunny, Daffy Duck, Porky Pig, Sniffles, and Yosemite Sam. The publication of this interview, as well as the release of Bugs Bunny: Superstar, drew the ire of Chuck Jones, who responded by writing a letter (dated 11 December 1975) and enlisting Tex Avery to make annotations (dated 22 December 1975). Jones's letter, which was publicly circulated, refers to "the grossly unfair misrepresentations of BUGS BUNNY SUPER STAR," adding,
Bugs Bunny: Superstar was first released in theaters in late 1975. At the time of the film's release, the rights to the individual cartoons themselves were controlled by United Artists as part of their acquisition of the pre-1950 Associated Artists Productions (AAP) library Warner Bros. films. The former AAP library was later owned by MGM/UA Entertainment Co., and eventually by Turner Entertainment Co. and Time Warner in 1996.
It was also available on laserdisc and VHS/Betamax format during the late 1980s but both versions were discontinued in 1999.
It was re-released on DVD on November 14, 2006, as a two-part special feature in the box set Looney Tunes Golden Collection: Volume 4. While most of the individual cartoons had been previously released as separate, refurbished entries in the Golden Collection, Bugs Bunny: Superstar was not restored, with some age wear apparent from the original film stock. All but two cartoons were replaced by versions created by Turner Entertainment in 1995. The Old Grey Hare used an original AAP print (evidenced by the AAP opening soundtrack) to preserve the ending gag involving the "That's all, Folks" title card, which was lost in the Turner updated version. I Taw a Putty Tat was also restored to the AAP print, as the Turner version contained an edit to remove a blackface gag.
On November 15, 2012, Warner Home Video released the documentary on DVD as part of the Warner Archive Collection. This version includes audio commentary by Larry Jackson. Reviewing the Bugs Bunny: Superstar DVD in 2012, animation writer Thad Komorowski wrote,
