One of the most important contemporary American artists, Alex Katz is the fascinating subject of this documentary. His signature style of flat-surface realism is captured here on video by his son Vincent and daughter-in-law Vivien Bittencourt, who follow Katz during a day of completing a painting. His work style draws on years of experience and involves the utmost concentration. In Alex Katz: Five Hours, the artist is working on his painting "January III". With no dialogue, but with the evocative music of Meridith Monk, this video captures the essence of an artist and his commitment to the experience of painting.
