Garfield is going continental. He’s travelling across the pond - with canine sidekick, Odie - to surprise his master, Jon Arbuckle (Breckin Meyer) who is in London to propose to his girlfriend, veterinarian, Liz Wilson (Jennifer Love Hewitt).

In the land of Big Ben, Buckingham Palace, Scotland Yard and fish and chips, Garfield’s British invasion takes on a Prince and the Paw-per dimension. He inadvertently switches places with Prince, a royal cat (and by luck, his exact look-alike), who has just inherited Castle Carlyle from his deceased owner, Lady Eleanor. This is a huge disappointment to her dastardly nephew, Lord Dargis (Billy Connolly).

Now living as the Cat of Carlyle, Garfield has a butler, Smithee (Ian Abercrombie), and an international array of servants and subjects, including Winston a (very) British bulldog; McBunny, a Scottish hare; a Punjab ferret; Bolero, a Spanish bull; I Claudius, a Shakespeare quoting mouse and Christopher, a French goose.

Meanwhile, prince is living the simple life of a commoner, hitting the pubs with Jon and Odie, getting his first taste of lasagne…and liking all of it.

Uneasy is the head, however, that wears the crown. Lord Dargis, who is next in line to inherit the estate wants Prince/Garfield out of the picture. Garfield’s bigger, better more purr-fect world is soon turned upside down in this tale of two kitties.
