The Pursuit of Happyness (2006)

In 1981, San Francisco salesman Chris Gardner invests his entire life savings in portable bone-density scanners, which he demonstrates to doctors and pitches as a handy improvement over standard X-rays. The scanners play a vital role in Chris’s life. While he is able to sell most of them, the time lag between the sales and his growing financial demands enrage his already bitter and alienated wife Linda, who works as a hotel maid. The financial instability increasingly erodes their marriage, in spite of them caring for Christopher Jr., their soon-to-be five-year-old son.

While Gardner is trying to sell one of the scanners, he meets Jay Twistle, a lead manager and partner for Dean Witter Reynolds, and impresses him by solving a Rubik’s Cube during a taxi ride. After Jay leaves, Gardner lacks the money to pay the fare and chooses to run instead, causing the driver to angrily chase him into a BART station. Gardner boards a train but loses one of his scanners in the process. His new relationship with Jay earns him the chance to become an intern stockbroker. The day before the interview, Gardner grudgingly agrees to paint his apartment so as to postpone being evicted due to his difficulty in paying the rent. While painting, Gardner is greeted by two policemen at his doorstep, who take him to the station, stating he has to pay for the numerous parking tickets he has accumulated
