I wonder what he did in his last "off" year, 1981.
EDIT: Wikipedia has this about 1981
In 1981, Allen's play The Floating Light Bulb opened on Broadway. The play was a critical success and a commercial flop. Despite two Tony Award nominations, a Tony win for the acting of Brian Backer (who won the 1981 Theater World Award and a Drama Desk Award for his work), the play only ran for 62 performances.
So, how many of these were acual great movies? I have counted 13 great movies out of the 35.
