Many theater directors have wrestled with the most difficult works of Shakespeare, Albee and Stoppard. Only one we know of has done them to critical acclaim with actors under the age of 16. Jeff Swearingen is director and resident playwright at Fun House Theatre and Film, the all-youth company he founded three years ago with partner Bren Rapp. He takes the craft and art of acting seriously and is passing along all he knows to budding actors, some as young as 6, who clamor to be in his Fun House shows. This summer he wrote and directed two new comedies, Game of Thrones Jr. and Stiff, which both sold out their two-week runs. Strict about behavior when he's working, Swearingen allows no flip-flops, food or texting at rehearsals. Now if only he could direct the audiences.
