I don’t remember where I found the first photo, but it shows the Kallet Capitol Theatre, now Rome Capitol Theatre, in Rome, New York. Note the two Disney movies on the right side of the marquee: Snowball Express (1972), a staple at elementary schools across America throughout the 1970s, and The World’s Greatest Athlete (1973).
The second photo, from the Seattle Post-Intelligencer, shows The Exorcist UK premiere at London’s Leicester Square Theatre on March 13, 1974. It’s playing with Enter the Dragon. Remember that the next time someone says movies today are just as good as they used to be.
The Exorcist remains the most unforgettably frightening movie ever made, in my opinion, although I still think Jaws is the greatest horror movie ever made. The video below shows many more marquees and premieres, as well as audience reactions to the blockbuster, including lots of fainting.
