Chita Rivera in "Kalamazoo?" 

This 2006 feature film had a very very limited regional release and no dvd as of yet! Chita played a beyond-the-grave granny along with The Nanny's Renee Taylor, and british acting legend Claire Bloom.
Upon returning to their hometown for their ten year class reunion, three women learn that a time capsule containing predictions about their futures will be opened. This brings to surface feelings of misdirection and lack of accomplishments in their life, and reveals secrets as well. The spirits of their three dead grandmothers try to help out.
