During rehearsals for the shoot, Coppola realized that things needed to be changed: "One of the important roles in the script is a mentor and teacher to Tetro (Vincent Gallo), and I originally wrote it for a man. As I read and reread (the script), I felt that the interaction between the two characters would be far more intriguing if they were of the opposite sex." However, other sources have told THR that Bardem "became unavailable." This could be true, as the actor wasn't available for the rehearsals in Buenos Aires. But if it is, why not say as much?
Whatever the case, you can be sure that Maura will give a very different performance than Bardem would have -- just like Gallo will definitely bring something very different to the table than Matt Dillon. The film follows Tetro, a man living in Buenos Aires and being mentored by Maura's literary critic, when his estranged younger brother (Alden Ehrenreich) comes to find him. Production began on March 31.
