Alcoholics?
Let me just start by saying this movie is grossly underrated and one of my all time favourites. I'm watching it again at the moment and I've just noticed there seem to be hints to both April and Frank having an alcohol problem.
Near the beginning of the film, April is seen taking out the trash. Mendes makes a point of showing her throwing away several large bottles of alcohol. She then rumenates on 'happier times'.
I noticed that frequently throughout the rest of the film the two are seen casually drinking together, especially when they are happy around one another (a rare occurrence in the film, needless to say!). Are they jovial/able to stand one another due to slight inebriation?
Were Frank and April alcoholics? Or did they have a substance abuse problem, that contributed to the dissolution of their marriage?
