I definitely want to see The Glass Castle based on the memoir by Jeannette Walls.
Tulip Fever based on the novel by Deborah Moggach is another film I will see. Though I haven’t read the book, I loved the film of her book The Best Exotic Marigold Hotel.
And anything with Judi Dench is worth seeing so Victoria & Abdul will get me into a cinema.
One film that is not mentioned that I will definitely see is Our Souls at Night based on the novel by Kent Haruf. Jane Fonda, Robert Redford, and Bruce Dern appear in this drama about the relationship that quietly grows between widow and a widower who live next door to each other. It will have its world premiere at the Venice Film Festival on September 1. See my review of the book at https://schatjesshelves.blogspot.ca/2015/07/review-of-our-souls-at-night-by-kent.html.
