All right, Moon Doggies. It’s officially the summer of surf. Now that Disney’s animated ”Lilo & Stitch” has indoctrinated the kiddies into the thrills of sweet swells, get ready for ”Blue Crush.” In this babes-on-boards drama (due Aug. 16), Michelle Rodriguez and (above) newcomers Sanoe Lake and Kate Bosworth follow Gidget’s footprints in the sand, except with a lot more action (and a little less Lycra). So tune your ukulele, wax up your longboard, and don’t forget a dollop of white goo for your nose, as counts down the surf-shredding scenes that score a perfect hang-ten.
