AN EVENING WITH BATMAN AND ROBIN played in San Francisco in December 1965. It played in the Presidio Theater, which normally played tame, soft core porno films. During one of the breaks there was an announcement over the PA system for all the kids to leave the auditorium during the break, and you could hear an excited rustle go though the attendees. The trailer did have some nude scenes which made the evening even more fun.
