This movie is all about psychological inflexibility. Warren Schmidt (magnificent played by Jack Nicholson) is a man who's identity is built around his work (he is vice-president of an insurance-company). The film starts with his retirement's party: beautiful words spoken, compliments given..., but only one day later he discovers that he's not welcome anymore at the office, and all his work ends up in a garbage can. Soon after that his wife suddenly dies, and although he feels like a prisoner in his marriage for over 42 years, he loses in a short time everything.
From that moment on his orderly life becomes chaotic and impulsive. He start's traveling with his king-size camper, visiting his daughter, finding out that he has never connected to her because of his work and now she doesn't need him anymore. He's afraid of intimacy and is running away from it or he spoils the moments were it's growing. He can only connect to his "true" feelings in the letters to Ngudu, a foster-child in Africa he has adopted for $22 a month, and to whom he writes from time to time (although the child is to young to read his letters).
It is there where psychological flexibility starts, painfully facing the life he lived. I would say a movie about self-as-content, experiential avoidance, lack of values and impulsive behaviors.
Must-see!!!
