Today, I made an important donation to the Brattle Film Foundation. The Brattle Theatre, like all movie theaters, has been hit particularly hard in the Covid-19 crisis with movie-going essentially going down to zero. Looking at Box Office Mojo data for April through September, box office receipts nationally fell 98%. That’s not a misprint — theaters took on just two cents for every dollar they took in last year. It’s not looking bright for the first couple quarters of 2021 either.
