21. Sarah Danielle Madison
Sarah Danielle Madison’s acting resume took in parts in some big TV shows and movies. 90210, House and Jurassic Park III all saw her light up the screen with her presence – and that’s not even to mention her starring role as Dr. Sarah Glass in The WB’s 7th Heaven. Tragically, her death in 2014 curtailed what continued to be a promising career: Madison, who was born Sarah Goldberg, passed away in her sleep at just 40 years old.
20. Amanda Peterson
Can’t Buy Me Love star Amanda Peterson was an acclaimed young star back in the ’80s and could easily have capitalized on the promise she showed in the 1987 teen comedy. Just seven years later, though, Peterson would retire from acting completely and go back to school. Moreover, from then until her passing in 2015 she lived pretty much out of the spotlight, save for a few headline-making run-ins with the law, and that could be why her death at the age of 43 went unnoticed by many.
