A celebration of the beauty of nature observed through innocent eyes, Gabriel follows a boy, Peter Mayne, walking along riverbanks, looking out at the ocean, and traversing forests and fields. Shot by Agnes Martin in California, Colorado, and near her home in Taos, New Mexico, the silent sojourn is interspersed with excerpts from a recording of J. S. Bach’s Goldberg Variations and possesses a breezy, limpid quality. Martin wrote of the film, “I thought my movie was going to be about happiness, but when I saw it finished, it turned out to be about joy—the same things my paintings are about.”
