It’s hard to believe that Richard Linklater’s Boyhood world premiered nearly 12 months ago at Sundance, then went on to Berlin where it won the Best Director Silver Bear. But then, for a film that took 12 years to make, it’s fitting that it should have such a long career which has seen it showered with praise and prizes as we head towards the Oscars. Not only did the movie shoot for a dozen years to chronicle the coming-of-age of Ellar Coltrane’s Mason and his family, played by Ethan Hawke, Patricia Arquette and Linklater’s daughter Lorelei, the filmmakers also documented the process. In the featurette above, Linklater shares his inspiration for the film and how he came to cast the young Coltrane, while a young Lorelei gets in a critique of her dad’s films, and Arquette and Hawke share their experiences. Since just the beginning of this month, Boyhood has won Best Picture from the New York Film Critics Circle, the Boston Society of Film Critics and the Los Angeles Film Critics Association as well as Top Film mentions from the National Board of Review and the AFI. Check out the featurette.
