Have you ever finished watching West Side Story and thought, "Man, if the Jets and Sharks were on skateboards, that film would have been perfect?" Someone thought it, because the skate flick Thrashin' is essentially that. Cory (Josh Brolin) heads to LA to compete in a big downhill competition with his crew "The Ramp Locals." He meets the beautiful Chrissy (Pamela Gidley) and sparks fly. But she's the sister of Hook (Robert Rusler), leader of the Daggers, a group of punk skaters (who are actually skate legends Tony Alva, Christian Hosoi, Eddie Reategui and Jesse Martinez). The next thing you know he's skate-jousting in a ditch (as one does), and Cory breaks his arm. Even worse, the Daggers burn down Cory's ramp. If he won the downhill race he'd win enough money to build a better ramp, but how do you solve a problem like Chrissy? The Webster Film Series screens Thrashin' at 8 p.m. tonight at Schlafly Bottleworks (7260 Southwest Boulevard, Maplewood; www.webster.edu/film-series). Admission is $5.
