Richard Widmark died last week, and now Jules Dassin is dead. Those who know Dassin’s work only from the years of his association with Melina Mercouri—“Never On a Sunday,” “Topkapi”—will be astounded if they view the films he made just before and after his blacklisting. In particular, “Night and the City” (1950)—it stars Widmark as a two-bit hustler in the wrestling racket—is a revelation. Criterion offers it in an admirable package that includes old and recent interviews with Dassin. The story goes that as the House Un-American Activities Committee was about to summon Dassin, Darrel Zanuck sent him to London to begin “Night and the City”—with the instruction to shoot expensive scenes first so that the studio would be committed. Despite the rush (Dassin claimed not to have read the novel on which the script is based), the resulting film is breathtaking in its technique—high noir.
