Out 1, also referred to as Out 1: Noli Me Tangere, is a 1971 French mystery film written and directed by Jacques Rivette and Suzanne Schiffman.

The film's experimentation with parallel subplots was influenced by André Cayatte's two-part Anatomy of a Marriage (1964), while the use of expansive screen time was first toyed with by Rivette in L'amour fou (1969).

When asked why the film is called Out 1, Rivette responded, "I chose 'Out' as the opposite of the vogue word 'in', which had caught on in France and which I thought was silly.

In the case of Out 1, its anchors are two theater groups, each rehearsing Aeschylus plays (Seven Against Thebes and Prometheus Bound); no character is made the lead.

The Seven Against Thebes production employs a newcomer, Renaud, to assist, but he quickly seizes creative direction from Lili, who recedes in disgust.

Thomas brings in old friend Sarah to help with a creative block on Prometheus Bound, but she causes a rift and the play is abandoned when another player leaves for unrelated reasons.

After reading the letters, Emilie prepares photocopies of them for newspapers and asserts a scandal involving Pierre setting up Igor.

Since they are both Thirteen members, the group reconstitutes to prevent this, and Thomas, Etienne and ruthless lawyer de Graffe meet to discuss it.

Several characters retreat to Emilie's Normandy house, "the Obade" (another Balzacian reference, see "Ferragus"), where she breaks down in front of Sarah, confessing her love for both Colin (who had been courting her) and Igor.

Because he wanted the performances to have a level of realism, some takes include lines "fluffed" by actors, or other common "mistakes" such as camera and boom microphone shadows, as well as unwitting extras looking at the camera in exterior shots (including a well-known scene where two young boys doggedly follow Jean-Pierre Léaud along the street during an extended monologue).

Many of the rehearsal scenes, particularly those of the Prometheus Bound group, are composed almost entirely of long shots, although the film also contains more conventional editing elsewhere.

The work also includes stylistically adventurous techniques, including the shooting of long shots through mirrors (again developing from work in L'amour fou), shortcuts to black to punctuate otherwise continuous scenes, short cutaways to unrelated or seemingly meaningless shots, non-diegetic sound blocking out crucial parts of the dialogue, and even a conversation in which selected lines are re-edited so that they appear to be spoken backward.

First shown as a work in progress at the Maison de la Culture in Le Havre, the film was re-edited down to a four-hour "short" version called Out 1: Spectre, which is more accessible and available (although not widely).

It disappeared again into obscurity until 2004, when both Noli Me Tangere and its shorter version Out 1: Spectre featured in the programme on 1–21 June, in the complete retrospective Jacques Rivette Viaggio in Italia di un metteur en scène organized by Deep A.C. and curated by Goffredo De Pascale in Rome at the Sala Trevi Centro Sperimentale and in Naples at Le Grenoble.

In interviews, Rivette has explicitly stated that the work is meant to be seen theatrically "on the big screen", and apparently dislikes it being watched on television.

The website's critics consensus reads: "Time is an essential character in Jacques Rivette's Out 1, Noli Me Tangere, a brilliant 13-hour study of human relationships and an exploration of how a generation's dreams and ideals slowly fade as life goes ruthlessly by.
