Tear Jerker / The Fountain

• The entire film is very sad, but nothing is sadder than Tommy discovering that Izzy has died during the night. He was too busy with his research to notice - and then he realises that he wasted the time he should have been spending with her. Luckily he gets a second chance.
• Izzy trying to take a bath is a subtle one. Something so simple that she can't do without help because the illness is affecting her that much.
• During the credits, Mansell's haunting "Together We Will Live Forever" eulogises the characters, the film, and with the gradual reveal of a sky full of stars, symbolizing the stories of others (as Xibalba was for Tom), it's welcoming the viewer to process their own grief.
