The Pursuit of Happyness is a 2006 American biographical drama film based on entrepreneur Chris Gardner’s nearly one-year struggle being homeless. Directed by Gabriele Muccino, the film features Will Smith as Gardner, a homeless salesman. Smith’s son Jaden Smith co-stars, making his film debut as Gardner’s son, Christopher Jr.
The screenplay by Steven Conrad is based on the best-selling eponymous memoir written by Gardner with Quincy Troupe. The film was released on December 15, 2006, by Columbia Pictures. For his performance, Smith was nominated for an Academy Award and a Golden Globe for Best Actor.
The unusual spelling of the film’s title comes from a mural that Gardner sees on the wall outside the daycare facility his son attends. He complains to the owner of the daycare that “happiness” is incorrectly spelled as “happyness” and needs to be changed. Read more on Wikipedia.
