"Singalongs at the Castro This single-screen movie house is not just one of San Francisco’s most beloved landmarks, it’s also one of the country’s oldest operating movie theaters. The 1922 theater's Spanish Colonial exterior was designed to evoke a Mexican cathedral, while inside it’s all fantasy,with tassels, swags, and a ceiling that looks like a leather tent. In 2001, substantial upgrades and improvements were made to the theater’s 1400 seats as well as to the sound and screen technologies. While it’s a fabulous place to take in mainstream movies, indie and foreign films, oldies, double features, and entries from the San Francisco International Film Festival that unreels each April, the Castro's singalongs are loved by all. Dress up (costumes are encouraged) and sing along to classic films such as Grease , The Sound of Music, and Beauty and the Beast . No need to carry a tune: Just come with a singing attitude.
