From New Horizons:

Dear Aaron,

I am sorry to report that Roger will not be able to attend the Lovecraft Film Festival. Complications have assailed his latest project, and as a result, he will be out of the state filming for the month of September. He acknowledges the time you have spent helping arrange this event and regrets that he must now decline the invitation.

***
We will still show a 35mm print of "The Haunted Palace" starring Vincent Price.
