I saw The Odd Life of Timothy Green in the theaters this summer, and it was such a delightful way to spend an afternoon. This is a film that I could watch with my mother in law (She is very sensitive to any language or inappropriate scenes) and I could recommend with no fears to absolutely everyone.
A happily married couple is trying to have a child. On the day their doctor tells them to give up, they decide for one day to dream of what their child would have been like. That night Timothy unexpectedly shows up in their home, from the Garden. The mother is played by Jennifer Garner, who is amazing in this roll (as expected).
