I found (not a movie, but rather the book) Siddhartha by Herman Hesse to have a significant effect on my outlook. At one point the main character contemplates suicide but is ultimately saved when he realizes his life force is connected to everything in the universe and that his sorrow is just an emotion that can pass. Meditation and mindfulness play a key role in his life that I find inspirational. The overall tone of the novel is hopeful and peaceful. I sometimes carry the book in my bag and pull it out on the bus or when I am waiting for someone and I read my favourite passages.
The author also went through a period of depression which I think gives sensitivity and insight to his writing. I liked Siddhartha so much that I then proceeded to read Hesse's The Glass Bead Game, which deals with similar subjects of transcendence.
What movies have you seen recently that touched on the topic of depression in a thought-provoking and helpful way? Has there been a film touching on depression that has changed your perspective somehow or otherwise made you grow as a person? If so, which film and why was it helpful?
