Classic Cinema? Does that mean it has to be black and white?

We've recently viewed Casablanca, Citizen Kane, and That Thing You Do.  And I've talked about classical cinema; there as even been a power point (you can find it here).  The question is, do each of these films fit this moniker?  Your task is to discuss the relevance of this moniker for these films.  Make sure that you include specific examples as to how each film fits into the classical cinema category and that you write at least three hundred words.  It may be helpful to include a definition of classical cinema with your response.
