All of his novels are satires on some facet of American culture (homeowner associations, insurance, the postal service, Consumerism, etc.) and are very much focused on surface plot development (as opposed to internal character monologues) making them easily adaptable to the screen. They are all supernatural in some way (The Policy, for one, shares similarities with the Final Destination series).

George Romero would be a good choice to adapt one of his novels to screen because his films are very much like Little's novels in that they all contain some sort of social commentary. If done right, critics would eat them up and audiences would go for the graphic violence and sex they all contain.
