As a man flummoxed by more powerful forces around him in "A Serious Man," Michael Stuhlbarg's Larry Gopnik is reminiscent of another nice guy who lets others run roughshod all over him: Jack Lemmon in 1960's "The Apartment." Both films are ostensible comedies that harbor painfully dark stories, and both have endings that the viewer wouldn't expect. Photo: "A Serious Man" (above) and "The Apartment."
