The heart is not like a box that gets filled up; it expands in size the more you love.

The sci-fi romance film “Her” was director Spike Jonze’s solo screenwriting debut, and it’s safe to say he knocked it out of the park. The movie, starring Joaquin Phoenix and Scarlett Johansson, was nominated for Best Picture in 2013 and won the Oscar for Best Original Screenplay. It tells the story of Theodore (Phoenix), a man who falls in love with his artificially intelligent assistant, Samantha (voiced by Johansson). Theodore represents two of the film’s main themes: loneliness and isolation. Samantha brings him a ray of hope and helps to alleviate his depression, offering support through lines like this one, which reminds us that there is no limit to our capacity for love.
