It’s a more consistent and impressive feat than Michael Winterbottom‘s otherwise involving Everyday (similarly shot over a half-decade, it gained and lost five different DOPs and suffered a host of technical issues).
The movie is being hailed for its novel production, though in fact British director Michael Winterbottom beat Linklater to the punch with his superb, little-noticed Everyday (2012), chronicling a working-class family over five years.
(Michael Winterbottom’s 2012 film Everyday tried the same trick over five years – what a lightweight!)
Meanwhile, Michael Winterbottom spent five years filming with the key cast of Everyday in order to portray the effect of a father's imprisonment upon a growing family, while Lars von Trier began and then abandoned his now-defunct Dimension project, for which he had originally planned to shoot three minutes a year from 1991 until 2024.
The Up documentary series and Michael Winterbottom's Everyday (filmed over a five-year stretch) have tackled the passing of time on screen, but Boyhood is something of a different proposition.
