This is an article from the Philadelphia Inquirer briefly reviewing the films playing at each of the major Philadelphia theaters during the Christmas season, from “It’s a Mad, Mad, Mad, Mad World” at the Boyd to “Kings of the Sun” at the Goldman.  It is interesting to note that, in 1963, theaters made a somewhat long-term commitment to an individual movie (whereas today, most theaters play more than one film) so that the theaters in the article are often listed before the film that is playing.  By A.
