As we enter the dog days of summer we're sure to experience a few less then prime days. On those drearier days you'll have to trade your beach blanket for rough fabric or sweaty leather of the couch. You might be sulking if you can't head to the beach and sashay down the boardwalk, talking in the sites and sounds of the midway. Cheer up! There are other ways you can still get in some summer fun. So we've pulled five titles off or movie shelves that are sure to instill a few thrills and chills just like going to an amusement park or funhouse, even if you can't get there.
