I enjoy the song at the ending credits of Bojack Horseman. In this Netflix cartoon show, Will Arnett plays a has been, washed up actor from 1990’s sitcoms in which he plays a horse. I am comfortable with him this way, and it ranks among the face cards in a deck of Will Arnett-themed playing cards.
I came to this conclusion because I tend to always see Arnett as different versions of Gob Bluth from Arrested Development. In 30 Rock he played the villainous Devon Banks. Although wearing more expensive suits and even more frustrated at his own incompetence, Will just seemed to be playing a version of Gob that exists on a darker time line. So the cartoon version of Will Arnett in horse form is an easy re-calibration of him into the Bojack of Gobs.
