Who was the popcorn girl at the El Portal in North Hollywood? Well this was news to me when I visited the theater about five years ago to see Stephen Colbert and Amy Sedaris in the reading/play Wigfield, but it was "Cherilyn Sarkisian, now known as Cher."
You can take in a play there and see the tiny concession stand where Cher might have once doled out buttery popcorn and soda pop. Debbie Reynolds is there now: http://www.elportaltheatre.com/elportal.html
