I recently saw the "Publicity Brat" episode of "77 Sunset Strip" on Me-TV. The "brat" was played by 9-year-old Evelyn Rudie, who did a good job being a 9-year-old-going-on-30 year-old brat. She was a playing a child star who's career was on the rocks and scheming to get publicity. When I looked up Evelyn Rudie on the internet, it turned out that in real life, she had taken all of her money out of her piggy bank, took a cab to the airport, got on a plane to Washington, DC to go see Mamie Eisenhower to talk her into getting her a regular TV series. In the meantime her parents thought she'd been kidnapped. Apparently it was legal in the 1950s for 9-year-olds to buy airplane tickets.
Also, check out YouTube for her appearance on "You Bet Your Life."
