Holding a theater full of kids in rapt attention isn't easy. But it's one of the reasons we have such mad respect for Atlanta actress Danielle Deadwyler and her performances this year as Charlotte in Charlotte's Web and as August March in The Real Tweenagers of Atlanta: Final Assembly, both at the Alliance Theatre. Her energy, humor, and charisma radiated off the stage. When Deadwyler, as Charlotte, explained to Wilbur that she kills flies "because it's in her nature," the line became a plainspoken bit of broad philosophical wisdom. Deadwyler sprained her ribs in a school matinee performance during preview week of Charlotte's Web, and the central planned stunt, Charlotte on aerial silks, had to be removed on opening night. Still, the actress brought out Charlotte's determination, honesty, and self-sacrificing kindness despite her bruised ribs, proving that Deadwyler is a special effect in and of herself.
