The Fountain (2006)

As a modern-day scientist, Tommy is struggling with mortality, desperately searching for the medical breakthrough that will save the life of his cancer-stricken wife, Izzi.

The Fountain is a 2006 film directed by Darren Aronofsky that weaves together three different storylines, each set in a different time and place, yet all connected by a central thread. The first storyline takes place in 16th century Spain, where a conquistador named Tomas is on a mission to find the mythical Fountain of Youth. The second storyline takes place in the present day and follows a scientist named Tommy who is searching for a cure for his wife Izzy's brain tumor.

The third storyline takes place in the distant future and follows a bald, tattooed astronaut named Tom who is traveling through space with a tree that he believes holds the key to eternal life. The film is a meditation on the nature of mortality and the human desire for immortality, and is visually stunning and emotionally powerful.
