"Boyhood" also earned the admiration of other filmmakers and artists. Director Christopher Nolan named "Boyhood" as his favorite film of 2014, calling it "extraordinary". Writer-director Mike Leigh, while accepting a fellowship from the British Academy of Film and Television Arts in 2015, called it "the definitive independent film". Writer Joyce Carol Oates tweeted her support, saying: "It is rare that a film so mimics the rhythms and texture of actual life as "Boyhood". Such seeming spontaneity is a very high art." Poet and critic Dan Chiasson wrote in a contribution to "The New York Review of Books": "This is a great film, the greatest American movie I have ever seen in a theater. It is great for what we see, but it is even greater for its way of making real what we cannot see, or for suggesting that what we cannot yet see we might one day see." According to Canadian philosopher Howard Adelman, "["Boyhood"] is Huckleberry Finn for the twenty-first century, for it is only Mason Jr. who retains his honesty, integrity and sense of decency throughout ... a masterful movie not to be missed." Alejandro González Iñárritu, winner of the Academy Award for Best Director in 2015 and Linklater's fellow nominee, said that when he watched "Boyhood", he sent an email to Linklater and thanked him for giving "this incredible gift".
