Here's a picture that works beautifully on several levels, including the philosophical (I kid you not). Approach it as a lighthearted caper, and you will be entertained. If you enjoy whimsy with a trace of fantasy, it will not disappoint you. How about a picture questioning the nature of reality, in which characters challenge and re-shape the identities that life seems to have foisted upon them? There are not many movies with such powerful ambitions, and fewer still that develop them in an oblique, yet perfectly comprehensible, manner. There is nothing the least bit heavy handed about this film; quite the opposite. Enter the special world it creates, and you will be rewarded both emotionally and intellectually.
(See what I mean? Now make sure you haven't missed "Finding Graceland" and "Pennies From Heaven.")
