Joy Ride (2001) It's all fun and games when two brothers (Paul Walker and Steve Zahn) take off on a cross-country road trip to bring home a pretty college friend (Leelee Sobieski). But the jokes end when a prank backfires and they find themselves stalked by a vengeful trucker. It soon becomes clear that the relentless psycho won't give up his chase until somebody pays with their life. Matthew Kimbrough, Leelee Sobieski, Steve Zahn...TS suspense
I've seen it a billion times and could watch it a billion more.
Starring Julia Roberts and Sally Field !
