A movie about inbred redneck hillbillies should go in one of two directions: it should either be an exercise in cult-movie camp, or it should be a modern day version of Deliverance (whose title one character is foolish enough to invoke at a certain point).
Broad nods to “Deliverance” and to the original “The Texas Chainsaw Massacre” abound, but they just make the movie worse--there are no comparisons.
In his DVD commentary with Dushku and Harrington, Schmidt repeatedly insists that Wrong Turn has a seventies sensibility, and like the film itself (in which Jeremy Sisto's character rhetorically asks of his companions, "Haven't you seen Deliverance?"), the director acknowledges its sources.
It's just possible that McElroy thought that because he actually stuck in a dialogue reference to John Boorman's Deliverance that his script would both look less like a splatter-film rip-off of that movie and attain some weight by virtue of association.
The kids invoke Deliverance by name at one point, but in its stripped down narrative thrust and its level of sustained suspense, the film it most vividly recalls is Walter Hill�s masterful bayou thriller Southern Comfort.
There’s a needlessly blatant “Deliverance” reference which winks and nods to the audience too much.
