There were also telephoned threats against individuals involved in the production.īecause of the threats, Teatro Nuevo, the Miami theater company that was to perform Miss Prida's 40-minute comedy, canceled the performances and the drama festival became a centerpiece in a heated debate over politics and the right to artistic expression. Some Cuban exiles in Miami have denounced Miss Prida for her efforts a decade ago to improve relations with Fidel Castro's Cuba, and bomb threats were directed against the Museum of Science, where ''Coser y Cantar'' (''To Sew and Sing'') was to be performed this weekend along with two other plays by Cuban exiles in Miami's first Festival of Hispanic Theater. And campus security guards at the door were frozen-faced when they searched everyone entering the building for weapons or bombs. They were undercover police officers whose interest was not in the play but in making sure no disruptions occurred. Some in the hall found no humor in the production, however. It is a comedy, and when the play was read by two actresses in a lecture hall last night at Miami-Dade Community College, the audience of 150, mostly young Hispanic people, laughed at the warring elements searching for accommodation in the same person. In Dolores Prida's bilingual one-act play, ''Coser y Cantar,'' the Cuban-born New York playwright puts two actresses on stage to represent one Hispanic woman torn between her cultural roots and her growing Americanization.
