When it was finished, I put in THE MAKING OF GONE WITH THE WIND. This two hour documentary is pretty definitive. I just wish they had shown us ALL of the screen tests in this release instead of the usual excerpts. I'd like to see every scrap of film on Vivien Leigh and Paulette Goddard.
I also think Selznick was hard on Jeffrey Lynn who gave a good reading of Ashley (Douglass Montgomery had some good moments in his Ashley scene, too), and he certainly would have been closer to the right age than Leslie Howard. Of course, he wasn't (and never would be) a star.
