I believe I'm a fairly decent authority on Austen's works, though by no means an expert. However I've watched and read the books enough times that I think I can do a fairly accurate critique.
Also, I've had quite a bit of experience in film production (including scriptwriting) so I will be bringing those skills to this analysis as well.
Areas I would like to examine are:
First of all, I will say up front that I enjoy the 2005 version better. Both versions have their strengths and weaknesses. However I want to acknowledge that bias up front.
Also, it is extremely important to point out that they are not both movies. The A&E version is a mini-series. the 2005 version is an actual film. This is most important in the screenplay section and I will discuss this differance in more detail there.
For now I will say that the main differance between the versions (besides the length) is that the A&E version is more of a "play" whereas the 2005 version is much more realistic. In my comparisions I will explore just what makes the one feel more "real" than the other. I will also discuss which one is more true to Austen.
So if you haven't watched both versions yet, go do so, then come back and get ready to comment! I'm sure there will be a lot to discuss!
