Variety:

Apple TV Plus will not be moving ahead with a second season of “Mr. Corman,” A24’s schoolteacher drama starring Joseph Gordon-Levitt, the streamer has confirmed.

As far as I know, this is the shortest run of a show on Apple TV+. Even Planet of the Apps (technically not an Apple TV+ show, but still) was alive for a full year, premiering in June 2017, officially canceled in July 2018.

Apple’s relationship with Joseph Gordon-Levitt continues with his exec produced, animated “Wolfboy and the Everything Factory.”
