Tom Holland has described his work on this series as "the hardest job I've ever had, but equally probably the most rewarding."
James Cameron attempted to make this into a feature film in the '90s, starring John Cusack. In Cameron's own words: "I entered an arrangement with a partner. We had joint control of the material. This partner turned out to be someone I couldn't work with and who felt that they couldn't work with me. We parted ways. A script had been written, we'd cast John Cusack to play the guy, and I was in pre-production. I was ready to go shoot... I will say that I believe this person behaved very unprofessionally. I also got to know Billy Milligan, and he got in the middle of this whole thing because he wanted his story told. He was running around creating more chaos, filing lawsuits. It turned into madness. We kind of got to be friends, but ultimately Billy contributed to the downfall of the project, at least in its incarnation with me. I sort of didn't want to tell his story anymore, you know?"
