The theater in Oxford Valley Mall P.A. early 80's...
That's funny, maybe I saw you there. I saw a bunch of movies there as a teenager in the 80s.
As far as my first cinema/theater, I have no idea. First one I remember is the drive-in in Orange, TX, ca. 1976. The movie was YOUNG FRANKENSTEIN. I had seen movies in theaters before then (the usual Disney stuff), but I don't have any memory of them.
