The Mouth Agape (1974) review

When Monique (Monique Mélinand) is diagnosed with a terminal illness, at first she lands in the hospital but then they send her back home where she's cared for by her husband Roger (Hubert Deschamps), who owns a fabric store, and son Philippe (Philippe Léotard), who's married to Nathalie (Nathalie Baye) - while she's in a steady state of decline, they're prowling around town trying to sleep with other women.  This is an unflinching - if callous - depiction of suffering that understandably was not a "hit" at the box office due to its frank and grim nature, and the scenes where an emaciated Monique struggles to breathe are difficult to watch (although masterfully shot by Néstor Almendros).  The most peculiar aspect to it is how, after she finally passes away, her family members are emotionally devastated by it ... and it doesn't feel like they're putting on a show (apparently you can be a philanderer and still be in love).  Michael Haneke has expressed admiration for it, and you can see the influence it would have on 2012's Amour.
