For most people, the answer is “never.” For some of us, it’s “honestly... not that long ago.” It doesn’t get the same 80s nostalgia hype as Magnum, P.I., The A-Team, or Remington Steele, but Simon & Simon was a real hit back in the day-and somehow ended up one of the most underappreciated shows of that entire era.

By the late 40s and early 50s, Burt Lancaster was one of the biggest movie stars in the world. The hits, the money, the fame. He had it all. But behind the scenes, Hollywood was starting to push back hard—and Lancaster made a move no one saw coming.

Jayne Mansfield’s rise in 1950s Hollywood was marked by headline-making scandals, publicity stunts, and rumors of Satanic ties before her tragic 1967 car crash cemented her place in pop culture history.
