Yesterday brought about the home media version of contemporary comedy overseer Judd Apatow’s latest feature This Is 40 (2012), a divisive work that has many examining (and questioning) the director’s status as an auteur and cultural talking-point of class and privilege.

The dvd/bd release of Apatow’s previous film, 2009’s Funny People, contained a production diary feature as an extra, and you can watch that behind-the-scenes documentary in the video embedded above.

The feature-length diary/behind the scenes documentary is an intimate look at the production of the film. It covers its intensive rehearsal process, including a stand-up comedy tour that preceded the film’s shoot, and a closer look at Apatow’s comedic and filmmaking philosophies (shaped by his deep admiration of John Cassavetes and mentor, Garry Shandling)
