This week marked the 163rd birthday of Vincent Van Gogh. In tribute, a look at the astonishing "Loving Vincent," the first feature-length painted animation, an 80-minute film made up of 56,000 oil paintings - or 12 hand-made paintings a second-long frame - created by over 100 artists in the singular style of Van Gogh. The Polish-British filmmakers, who are still looking to hire more artists, seek to tell the story of Van Gogh's troubled life and sudden death through his paintings and their subjects; the plot is drawn from 800 letters written by Van Gogh. Note the filmmakers, "Vincent wrote in his last letter, 'The truth is, we cannot speak other than by our paintings.' And that is what we are doing - letting his paintings tell the story of what the painter had inside his heart." The mind-bending trailer, hinting at that vision, was released last month.
