Even at only 14-minutes, LOVE LETTER TO EDIE packs in a lot of interesting stuff. My favorite being Edie telling her life story (who knows if it's even accurate) while we watch her and other Dreamlanders (Pat Moran, Mink Stole, Mary Vivian Pearce) reenacting those events or just walking around. I thought that was really cool and very nice of them to help with this short film.
If you don't care about Edith Massey or John Waters, then LLTE will probably be a bore, but if you are a fan then it's mandatory. Also, strangely enough, there's two different versions of the film out there. One looked to be the original (with audio commentary by Pat Moran) and an updated version that tweaked some of the credit stuff and had a slightly better picture. I personally like the original better.
