Ahoy, squirts! Quint here. This is a weird bit of recasting. Originally Javier Bardem was to star in Francis Ford Coppola's next flick, TETRO, but his schedule ended up not working out. Instead of just recasting, Coppola got to thinking about the character and decided to rewrite it to change the sex of the lead and has now cast Carmen Maura.

Fans of Alex de la Iglesia's work will remember her from LA COMMUNIDAD and 800 BALAS and fans of Pedro Almodovar's will remember her from VOLVER.

I don't know much about the story, but the Hollywood Reporter says this:

Maura will play a literary critic and mentor to Tetro, whose younger brother (Alden Ehrenreich) searches for him in Argentinia's capital city.
