The actor was a teen icon and heartthrob in the late 1980s, known for his roles in films like Lucas, The Lost Boys, License to Drive and Dream a Little Dream. While his more recent work has been more limited, that hasn't stopped fans from flooding Twitter and Facebook with responses to this news.
Haim is most prominently known for his work in the The Lost Boys -- a coming-of-age story about teenage vampires. The film, which was his first collaboraton with Corey Feldman, has become something of a cult classic, spawning a straight-to-video sequel in 2008, with another follow-up planned. Today, however, it's a trending topic on Twitter.
Because Corey Haim and Corey Feldman were frequently associated with one another, it's not surprising that for a brief period of time, "The Goonies" became a trending topic on Twitter as well. However, it was Feldman, not Haim, that starred in that classic.
Facebook groups like "R.I.P. Corey Haim (The Lost Boys)" are also sprouting up.
Haim, who suffered from drug addiction throughout the 1990s and 2000s, gained Internet attention in 2001 when he attempted to sell his hair and teeth on eBay (these auctions were eventually pulled down because they violated eBay's TOS, which states you can't sell body parts). He also starred in a reality show called The Two Coreys alongside Corey Feldman for two seasons on A&E.
