Another example of an ab exercise that works the hip flexors is any leg-raising exercise done in a supine (laying face up) position. Again, this movement works the hip flexors far more than the abs and shouldn't be done until you have good abdominal strength.
Behind the scenes Edit. The town of Santa Cruz was used as the town of Santa Carla for the original 1987 Lost Boys film. Fictional Santa Carla is based on Santa Cruz where much of the movie The Lost Boys was filmed. Santa Cruz is located on the north end of Monterey Bay, CA. The Lost Boys: The Tribe was set in the fictional town of Luna Bay, CA (filmed in Vancouver, BC). Lost Boys: The Thirst was set in also fictional San Cazador, CA (shot in South Africa).
The above opening scenes, first one, was shot at the Janss Conejo Ranch, and the close-ups of the boys were at Chavez Ravine, California. The opening ride-up shots were filmed at Janss Conejo Ranch while filming the pilot episode in April of 1959. The region was urbanized into the community known as Thousand Oaks in 1969. The rugged Santa Susanna Mountains still provide a lovely backdrop, even in today's times.
