In recent years, Martindale has also attracted a surprising number of film scouts that have been attracted to the town's turn-of-the-century charm. As a result, various television shows, music videos and movies have been filmed in town most notably: A Perfect World, starring Clint Eastwood and Kevin Costner; The Newton Boys, starring Matthew McConaughey and Ethan Hawke; and New Line's 2003 remake of The Texas Chainsaw Massacre. Over the years, each subsequent film crew has left its mark on the town. A strand of wood beams sits on a vacant lot next to the bank—all that remains of a saloon that was constructed for one of the westerns.
