I heard an interesting thing that Paul Scheer mentioned on a recent "How Did This Get Made" podcast:
Apparently, all of Tig Notaro's scenes were filmed after the movie was done. The actor originally in the movie was kicked off and she came in and filmed all her scenes in front of a green screen alone and was digitally inserted over the other actor. She had zero interactions with any of the other actors in the movie.
