In this simple language activity, students employ Portuguese and content knowledge to create a short dialogue that imagines what characters in the film Four Days in September are saying. Four Days in September is a Brazilian film based on Fernando Gabeira's book O que é isso, companheiro? After reading selections from O que é isso, companheiro? and watching parts of the film in previous classes, students watch a short excerpt without sound. In pairs or groups of three, they then work together to write a dialogue from the point of view of characters. This activity can be used as a grammar review by requiring students to use certain constructions. After composing the dialogue, students share with the class. Students might just read the dialogue aloud or act it out. The instructor corrects any language problems.
