Corey Haim – Pneumonia

Actor Corey Haim was a very popular teen star back in the ’80s, well recognized for his roles in The Lost Boys, Dream a Little Dream, and License to Drive. He and actor Corey Feldman were also known for starring in their very own reality show called The Two Coreys.

Sadly, Haim became addicted to drugs as he got older, and he never really overcame it even with professional help. Though he died in 2010 of pneumonia, he was reportedly abusing prescription pills at the time as well. He appeared posthumously in the 2014 movie The Dead Sea.
