Replying to @Angie The Hippie Alfred Hitchcock's "The Birds" was filmed right here on Union Square!! 🐦‍⬛🐦‍⬛🐦‍⬛ I love his movies since they instill a sense of fear without being gory. 🐦‍⬛ You can catch a screening of The Birds on Oct 4th at Union Square, totally free! #sanfrancisco #unionsquare #AlfredHitchcock #onlyinsf #spookyseason
