The Lost Footage of Marilyn Monroe

The story of the night Marilyn Monroe’s white halter-top dress blew up was well known among Jules Schulback’s children, and even among his grandchildren. His granddaughter Bonnie Siegler said he bragged from time to time about his personal film shoot with Marilyn.

“He was a real raconteur,” said Ms. Siegler, a graphic designer who runs her own company, Eight and a Half. “I didn’t know if the story was real.” But even though she had never seen it, she often told people that her grandfather had footage of Marilyn Monroe on the subway grate.
