In the summer of 1974, A. Bowdoin Van Riper had just gotten out of school when Hollywood came to town.

Van Riper, then 11 years old, went down to the beach on Martha's Vineyard with a friend to watch the filming of what would become Steven Spielberg’s “Jaws." When a crew member called out for volunteers, the two raced into the water and pretended to panic for a scene in which two kids frighten swimmers using a cardboard fin.

“It was a very, very short brush with Hollywood, but it is still − after 50 years − cool to know that I played a very, very, very small part in helping the film get made,” Van Riper said.

Like many locals who helped create the first summer blockbuster, Van Riper is now gearing up for an elaborate, summer-long celebration of the 50th anniversary of "Jaws."

Upon its release on June 20, 1975, “Jaws” struck fear in the hearts of beachgoers nationwide, leading to an increase in shark phobias and trophy hunting that helped decimate shark populations. Though viewers say the movie scared them away from beaches, pools and even bath tubs for a time, that fear has become an American fascination.
