Lee Child says that adapting *61 Hours* for Prime Video’s *Reacher* could be unusually difficult because the story depends on a vast, snow-covered landscape. The weather creates the isolation and danger central to the plot, so removing it would fundamentally change the story.

Published in 2010, the novel strands Reacher in the South Dakota town of Bolton after his bus crashes during a snowstorm. He becomes involved with local police and a witness whose testimony threatens a criminal operation. Child says reliable snow would be hard to secure for filming, while footprints in pristine snow would make repeated takes difficult.
