Four disparate films starring Barbra Streisand -- The Main Event, Nuts, Up the Sandbox, and What's Up, Doc? -- are brought together for this four-DVD collector's set. What's Up, Doc? and The Main Event have both been widescreen transfers at the aspect ratio of 1.85:1, which is letterboxed on conventional televisions and enhanced for 16 x 9 playback on widescreen monitors. The films' original English-language mono soundtracks are mastered in Dolby Digital, as are alternate soundtracks dubbed in French. The discs also includes optional subtitles in English, French, and Spanish. Nuts features the same technical specifications, except that the English-language soundtrack is in Dolby Digital Surround, and the French-language track is in Dolby Digital Mono, while Up the Sandbox also includes the same features as What's Up, Doc? and The Main Event, except for the absence of a French-language audio track.
