With the new 'Arthur' starring Russell Brand in theaters Friday, take a trip back to the '80s original that started it all, now on Blu-ray in a two-movie collection. Dudley Moore plays the title character, an irrepressible and irresponsible playboy millionaire who must choose between marrying a woman he despises and a girl from the wrong side of the tracks (Liza Minnelli). John Gielgud stars as Arthur's acerbic valet in a role that earned him a Best Supporting Actor Oscar. In 'Arthur 2: On the Rocks,' Dudley Moore faces having to get a real job after a business deal bilks him out of his fortune.
