From Marietta and Alpharetta to Fairburn and Tyrone, more than a dozen of the most notable community theaters from outside the Perimeter of Atlanta are winding down their current seasons and gearing up for their next ones.

Whatever these smaller avocational groups lack in annual budgets or general production values compared to the professional companies intown, they often compensate with enthusiasm and gutsiness.

Snellville’s New London Theatre plans to stage no fewer than 11 shows during its 2013-14 season, for example. And Newnan Theatre Company will be tackling everything from the epic drama “August: Osage County” to “Thrill Me,” a dark musical about the scandalous Leopold and Loeb case.

Here’s what’s in store for audiences this summer and beyond.
