Following a series of films for theatrical productions, Guzzetti’s experimental short film, Air, won first prize in its category at the 1972 Chicago Film Festival and was followed by another experimental short, Evidence (1972). Afterwards Guzzetti embarked on an autobiographical cycle that included the feature-length Family Portrait Sittings (1975) and Scenes from Childhood (1980), both premiered at the Whitney Museum of American Art. These led to further autobiographical films, including Time Exposure (2011) and the recent The Gifts of Time (2018), as well as to collaborations with the photographer Susan Meiselas and filmmaker Richard P. Rogers, with whom he co-directed Living at Risk: The Story of a Nicaraguan Family (1985) and Pictures from a Revolution (1991). These were political and historical documentaries and prompted later collaborations with Susan Meiselas on Reframing History (2006) and A Family in History (2011), a two-DVD set that includes Living at Risk plus a group of 20 short films entitled The Barrios Family 25 Years Later. In the late 1980s Guzzetti began a series of conversations with anthropologist Ákos Östör that resulted in Seed and Earth (1994), a portrayal of life in a Bengali village, and Khalfan and Zanzibar (1999), which poses the question of an individual’s relation to his culture. Both of these were made collaboratively with Östör and anthropologist Lina Fruzzetti. Around 1993 Guzzetti became interested in the experimental possibilities of the new small video formats and began a series of tapes that include Rosetta Stone (1993), What Actually Happened (1996), Under the Rain (1997), A Tropical Story (1998), The Tower of Industrial Life (2000), which was selected for the 2002 Whitney Biennial, Down from the Mountains (2002), Calcutta Intersection (2003), América Central (2004), History of the Sea (2004), Still Point (2009), Renewal (2015), Passage (2018) and The Falcon Cannot Hear the Falconer (2020). This experimental strain is related to his work with composers, including his contributions to Earl Kim’s Exercises en Route (1971) and to Kurt Stallmann’s SONA (2005) and Moon Crossings (2011). He has also worked collaboratively with Stallmann on Breaking Earth (2008), a gallery installation for 11 channels of sound and 5 video projections, Time Present (2013), and Among Rivers (2019), for 4 performers, 28 loudspeakers, and 7 video projectors. He collaborated with Ivan Tcherepnin on the 16mm Sky Piece (1978).
