With two large theaters, a basement cabaret, and several smaller stages in its large downtown building, ACT is simultaneously one of Seattle's large regional theaters and a home for smaller, more experimental work. It is known for populist programming (such as its holiday production of A Christmas Carol), a traditional season of major plays (from world premieres by local writers such as Yussef El Guindi to national works by the likes of Christopher Durang and Will Eno), and new work by smaller companies as part of ACT's Central Heating Lab program.
