You can read a little more of the backstory between Carl's book and Mr. Franco here.
"I'd been discussing the idea [of doing a soap] with this artist named Carter. He's a friend of mine, and I collaborate on different projects with him. We were going to do a movie called Maladies that he was going to direct and I was going to star in, and I was going to play a character who was formerly on a soap opera. And that got us talking about, what if I actually was on a soap opera? Wouldn't that be interesting? People would be surprised. Nobody would expect it. And also, it's a different kind of entertainment and acting and yeah, people often look down on soap operas as kind of inferior entertainment. But I was thinking in a different way at that point.
I had just read this book by Carl Wilson ... about Celine Dion. And he wasn't a fan of Celine but he decided he was going to investigate why. Why does he feel superior to Celine's music? And he didn't come to any definite conclusions, but he figured out that Celine's music means something to some people and gives a lot of people strength, hope — whatever you get from music. So he decided to suspend his judgment and stop looking down on Celine just because she doesn't speak to him. So that's kind of the mindset I was in at that time."
