Spanish A-level Film and Book Help - Mujeres + El Otro Arbol

Hi, I am studying mujeres al borde de un ataque de nervios for my spanish film, and need some help. I can not, for the life of me, find any revision resources online, and am quite unsure how to revise for the film. Ideally, I'd like to get an A*/A for Spanish alevel and was wondering if anyone can help with how to revise for the film in general, or for my film specifically, if someone else has done this. I am in the same situation with my Spanish book, so advice for this also would be greatly appreciated. (my book is 'el otro arbol de guernica')
Also, my exam board is Eduqas.
