Auntie Mame is my favorite movie EVER. I do have to note I am speaking about the Rosalind Russell version. There is nothing wrong with Lucille Ball, but her version of the movie was terrible.
Mame is an inspiration. She was avant-garde for her times. She embraced life and every day was a party for her. If there is one concept to glean from the movie, it is to make the best of what you have, no matter the consequences.
