On Tuesday night, Kilmer, an outspoken and lifelong Christian Scientist, shared on Facebook that Douglas wrote the 56-year-old actor "a nice note apologizing" for suggesting to the press overseas that he "wasn't doing too well."
"[He] was grateful to hear I am doing well," Kilmer wrote. "He's a classy guy."
The Kiss Kiss Bang Bang star also recounted how he first met Douglas. "[Director] Oliver Stone insisted I meet him, knowing what Michael would say about Oliver torturing him during Wall Street," Kilmer recalled. "It was hilarious and Oliver was relishing reliving Michael's pain. It all worked out and all was forgiven on Oscar night I believe."
Last week, Kilmer made his first public appearance since denying he has cancer, and had trouble speaking as he admitted that he did have health issues that forced him to cancel a tour. "I went into rehearsals down in Florida and started having trouble with my speech," he explained. "Obviously, I'm still recovering. My tongue swelled up and I canceled the tour. As I'm recovering I'm showing this."
