Along with frequent collaborator Jeffrey Perkins and Darryl L. Frank, he shared three consecutive Emmy nominations for Outstanding Sound Mixing for the show's final three seasons. They and others also earned Cinema Audio Society Award noms for those same seasons of the show, and Justen was part of the team that won the 2014 Motion Picture Sound Editors Award for Best Sound Editing - Short Form Sound Effects and Foley in Television.
In the Better Call Saul Insider Podcast, Vince Gilligan confessed that he "did not have a lot of fun directing" the first two episodes of season 3, because "it was very, very hard (...) directing two episodes back to back". The last time he did that was in season 4 of Breaking Bad (2008) (End Times (2011), Face Off (2011)) and he was "10% younger" and "that 10% make a great difference". However, he is very proud of these two episodes.
