Writer-director Peter Greenaway pays tribute to Sergei Eisenstein, the Soviet director of Potemkin (1925), with this quixotic jaunt, a feast for the eyes and ears that ultimately lacks substance. Imagining the director's transformative 1930 sojourn in Mexico, the film is staged on elaborate sets and against less impressive CGI backgrounds, with triple-split screens occasionally popping up to enhance Greenaway's droll expositions on the Russian Revolution or Red-scared Hollywood. The high points involve Elmer Bäck, as the closeted 33-year-old artist, and Luis Alberti, as the married professor who deflowers him, exchanging epigrammatic observations on sex and death. But melodic lines don't add up to a satisfying whole, and Greenaway gets lost in his own panache, allowing the narrative to unravel. In English and subtitled Spanish.
