Here's one from my archives!
It's supposedly true... I'd forgotten it in the mists of time, but it made me howl back in the day...
Pia Zadora, yank actress, star of much esteemed movies such as "Santa Claus Conquers the Martians" and the like.
She also appeared on the stage, and courtesy of....erm....a close association with the show's producer, managed to get the lead roll in a play about Anne Frank.
You'll no doubt know the story. Hidden in Amsterdam from the Nazis, her diary documents her day-to-day life in those extraordinary and dreadful times.
The audience didn't like Ms.Zadora's performance. It was, not to put too fine a point on it, dire.
There came a scene when some German soldiers raided the building where Anne was hidden.
Having suffered enough, some wag in audience cupped his hands to his mouth, and bellowed "She's in the attic!"!
Edit : Or even "role"! Tsk, tsk.
