Let's go to the (subtitled) movies

Notice the movie schedule at Robinson Theater is indicating that they are showing movies with English subtitles

Don't know if my recollection is accurate.  Do remember going to a movie while on R&R in Bangkok in 1966.  Do remember they had ashtrays in the theater then.  Seem to remember they had earphones for English language
