The Tony Award-winning American Conservatory Theater made its debut in 1967 and quickly established itself as the city's premier resident theater group and one of the nation's best. Numerous big-name actors have tread the boards here, including Annette Bening and Nicolas Cage. The A.C.T. season runs September through July and features both classic and experimental works. Its home is the fabulous Geary Theater, a national historic landmark that is regarded as one of America's finest performance spaces.
