Er wordt wel gezegd dat de eerste 21 jaar de carrière van een artiest bepalen. Er zijn maar weinig regisseurs die zo eigenhandig de filmwereld hebben opgeschud als de peetvader van de indie, Richard Linklater. Van het baanbrekende Slacker tot zijn vernieuwende Boyhood, Linklater heeft de grens van 21 jaar bereikt en zijn handtekening onvoorwaardelijk gezet in de Amerikaanse popcultuur. De documentaire bevat openhartige gesprekken met Ethan Hawke, Jack Black, Keanu Reeves, Billy Bob Thornton, Matthew McConaughey, Jason Reitman, Julie Delpy en anderen, waarbij hun verhalen tot leven worden gebracht door animatiescènes.
Nee, helaas is 21 Years: Richard Linklater nog niet beschikbaar op Netflix in Nederland.
