Before seeing a free showing of My Own Private Idaho, I heard the end of the lecture on the history of the Baghdad Theater. I arrived for the lecture during the period when the Baghdad was going through a transformation to a "multiplex" which meant walling off the balcony for a separate theater and shoehorning a third theater, called the Back Door Theater, behind the main theater space. All McMenamin's movie screens show slide shows before their movies begin, and interspersed with the slides for the many McMenamin's products are historic pictures. I have been seeing the picture of the Back Door Theater for years and wondered about it. Now I know.
This picture was a poster for a premiere that happened at the Baghdad: They Live. Among other things, this forgettable movie had the involvement of the man who invented the propeller beanie. Thus the explanation of the strange juxtaposition of these two pictures.
The history of the theater was quite interesting and I was sorry I didn't prioritize listening to the entire lecture.
