Comedy sequel in which the laziest cat in America swaps places with the richest feline in England. Jon Arbuckle (Breckin Meyer) is on his way to London to propose to his veterinarian girlfriend, Liz Wilson (Jennifer Love Hewitt), and his unflappable cat, Garfield (voice of Bill Murray), is determined to be there when Jon pops the big question. Of course, Garfield wouldn't go anywhere without his old pal Odie, and soon after arriving in the land of Big Ben, the clueless tomcat inadvertently changes places with royal look-a-like Prince. It seems that Prince's owner, Lady Eleanor, has recently passed away, leaving the care of her sprawling estate Castle Carlyle in the capable paws of her devoted kitty companion. The trouble is, Prince has decided it's time for a vacation, and with Garfield in charge there's no telling what kind of trouble will befall Castle Carlyle.
