Book to the Movie returns with C.B. Smith for one of our most anticipated episodes! We pit the 1983 film Of Unknown Origin starring Peter Weller against the novel The Visitor by Chauncey G. Parker III. Who does the giant rat horror better? We break down the spine-chilling action of the film and the psychological depth of the book. We're also finally putting an end to the gnawing debate – is it a giant rat or just kind of a big rat? Tune in to find out as we go Book to the Movie!
