colleague Corey Haim, 38. Feldman, who co-starred with Haim in movies such as "The Lost Boys," "License to Drive" and "Dream a Little Dream," said he was "in shock" over the news of Haim's passing and that he had seen the late actor as recently as "three or four days ago."

"He was fine," Feldman said when asked about Haim's appearance at the time of their last meeting. "He was actually giving me some advice about something I was very upset about. He was being very positive."

According to Feldman, reports that Haim died of a drug overdose are premature, citing other possible factors including kidney and heart failure, an inadvertent lethal mixture of prescribed drugs, or simply his body shutting down after years of drug abuse.

"Until the coroner's report comes out and until we get specific evidence and until we know exactly what the toxicology report says, nobody knows [how Haim died], and nobody is going to know," Feldman said. "We are aware of the fact that Corey Haim has a long and detailed drug history and battled addiction for many, many years. I know it better than anybody, because I've been the guy stuffing charcoal down his throat when he was [overdosing]. I've been the guy trying to make him stand up or say a complete sentence. I've been through it with him many, many times, and it's happened very badly and very intensely through the years."

While Feldman said he appreciated the outpouring of condolences from Haim's many mourning fans, he was disappointed that the late actor's support didn't reveal itself sooner.

"At the end of the day, where were all of these people the last 10 or 15 years of Corey's life?" Feldman asked. "Where were all of these people to reach a hand out to him and say, 'You're a legend. You're an amazingly talented and wonderful person.' "

Feldman said mean-spirited remarks from tabloid magazines and Web sites such as TMZ were quite troubling not just for Haim, but also for himself. In light of Haim's death, Feldman suggested that society needs "to grow up and think about every time we laugh at somebody in the tabloids, every time we poke a finger at somebody and say, 'They're a joke' or 'They're fat' or 'They're a drug addict' or 'They're washed up' or 'They're a loser,' we need to look at ourselves and say, 'Who am I?' "

Haim had filmed several movies prior to his death, Feldman said, including a celebrated role in "American Sunset." Feldman also revealed that before Haim's death, the longtime collaborators "were negotiating a deal to do [their] first movie together in nine years." Haim was apparently in the process of pitching a sequel to "License to Drive" called "License to Fly," which would have been followed up with a third installment called "License to Dive."

There are currently no funeral plans for the late actor, Feldman said, though he hopes to arrange a memorial service where members of Hollywood would pay their respects to the actor, citing "Lucas" and other films as reasons to fondly remember Haim's contributions to the industry.

"Hopefully, he's going to be remembered as a beautiful, funny, enigmatic character who brought nothing but life and light and entertainment and art to all of our lives," Feldman said.
