[5] In Teatro Amazonas (1999), an audience seated in the neoclassical opera house of the same name in Manaus, Brazil, looks back at the camera and the viewer throughout the duration of the film.

Photographed from a stationary camera positioned on the stage at the front of the theater, one unedited take shows the audience listening to a live performance by the Choral do Amazonas choir.

The musical score, an original choral composition written by Californian composer Becky Allen, begins with a solid chordal mass which gradually becomes silent over twenty-four minutes.

[9] Set in the backdrop of a rural village in California's Sierra Nevada Mountains, the feature-length 16mm film Pine Flat (2006) and large-scale portraits focus on the community's youth and the experience of American childhood.

For the series of nineteen portrait photographs of Pine Flat's youth, Lockhart set up a traditional studio in a nearby barn, where the children could sit in the historic method.

[14] The soundtrack, designed in collaboration with composer Becky Allen and filmmaker James Benning, weaves the diegetic tones created by worker's voices with industrial sounds and music.

In a series of filmic tableaux, Lockhart uses a fixed-frame camera to capture the improvisational, impromptu games that these children devise, shaping a visual testament to youthful resourcefulness.

Returning to Poland, Lockhart began to collaborate with Milena – a young woman who she befriended in Łódź during the production of Podwórka and had since stayed in contact with.

[18] This collaboration resulted in the production of a series of photographs as well as the film Antoine/Milena (2015) in which Milena reenacts the iconic final scene from François Truffaut's The 400 Blows.

Over the course of three summers, Lockhart, together with movement therapists, philosophers, theater directors, and pedagogues, would conduct a series of generative workshops with the girls of the Center.

[13] Lockhart and her work in Poland were the subject of a trilogy of successive exhibitions at the Centre for Contemporary Art, Ujazdowski Castle, Warsaw (2013), Bonniers Konsthall, Stockholm (2014), and Kunstmuseum Luzern, Lucerne (2015).
