Many were wondering if it would be included in the new movie version (it's not.) Here's what Stephen had to say:

"Stephen King, for his part, seem to find the whole affair mildly intriguing. In a new statement to Vulture, he says, "I'd just add that it's fascinating to me that there has been so much comment about that single sex scene and so little about the multiple child murders. That must mean something, but I'm not sure what."

Here's what Stephen has said about it in the past....

".....The sexual act connected childhood and adulthood. It's another version of the glass tunnel that connects the children's library and the adult library. Times have changed since I wrote that scene and there is now more sensitivity to those issues.

The bigger question is: WHY INCLUDE IT AT ALL IN THE BOOK VERSION!
