Already in the early 20th century there was the presence of theaters, entrepreneurs and actor companies, but paradoxically the quality of the products staggered, and only in 1940 the Brazilian theater received a boost of renewal thanks to the action of Paschoal Carlos Magno and his student's theater, the comedians group and the Italian actors Adolfo Celi, Ruggero Jacobbi and Aldo Calvo, founders of the ''Teatro Brasileiro de Comedia''. From the 1960s it was attended by a theater dedicated to social and religious issues and to the flourishing of schools of dramatic art. The most prominent authors at this stage were Jorge Andrade and Ariano Suassuna.
