Behind the scenes, however, Greene was battling his own demons. In a profile published in the November 1996 issue of PREMIERE, the lanky blond actor with piercing blue eyes revealed that he had run away from home at the age of 15. Living on the streets of NYC, he drifted into drug use and eventually drug dealing. Barely escaping from dealers who attempted to kill him, Greene hid out in theaters and drifted into acting, eventually excelling at portraying villains, all the while ingest various drugs from cocaine to heroin. Greene has admitted to attempting suicide in March 1996. Shortly thereafter, he sought treatment for his addictions.
