Dreamcatcher was the first book King wrote after his horrible road accident in 1999, and it was written mainly through a haze of painkillers. He’s since admitted the book is a mess for this reason, and he's not too fond of it.
This didn’t stop Warner Bros snapping up for a big budget feature, and they assembled an impressive cast for it, including Morgan Freeman, Damian Lewis, Tom Jane and Timothy Olyphant. Unfortunately, the whole enterprise was a disaster of conflicting tones, horrible CGI monsters that are literally pieces of s*** and jaw-droppingly poor ending.
Weirdly enough, King seemed to give the impression he liked Dreamcatcher during an interview for the DVD, but has since conceded it’s terrible, bluntly calling it a “train wreck” in a 2007 interview with Time.
