Although Albert Brooks only signed on to do four episodes, creator Jenji Kohan admired him and enjoyed the character so much that she tried to convince him several times to sign on for more episodes.
Albert Brooks (Lenny Botwin) and Alexander Gould (Shane Botwin) play grandfather and grandson. However they also voiced the characters Marlin and Nemo respectively in Finding Nemo (2003), playing father and son.
Alexander Gould (Shane Botwin) is noticeably taller and his hair is shorter despite this season picking up just after the last season ended.
The song during the end credits is "Se Puede" by Los Mono [sic].
