The first of a series of free outdoor movies will be shown at dusk Saturday at the beach area of Marion County Park and Lake.

This month’s movie has not yet been selected, but a similar showing the third Saturday in August will feature “Jaws” shown on a floating screen, with moviegoers asked to jump in the lake whenever the movie’s shark appears.

A similar event is planned for September.

Moviegoers should plan to bring lawn chairs or blankets.
