The times may have changed, but thankfully the traits remain that make ex-roomies Felix Ungar (Jack Lemmon) and Oscar Madison (Walter Matthau) the all-time perfect mismatch. Oscar is still an uncompromising slob who thinks a brown sock and a black sock is close enough. Felix is still a fussbudget who can't pass a spice rack without arranging it alphabetically. After years of going their separate ways, the two are together again, en rout to the wedding of Oscar's son to Felix's daughter. They've got the map, the rental car, a tankful of Simons's comedy zingers, and they're getting 1,000 smiles to the gallon!
