Marta Balaga “Holy Spider” breakout Zar Amir Ebrahimi and Guy Nattiv are set to make history with “Tatami,” the first feature co-directed by an Iranian and an Israeli filmmaker. Premiering in Venice Film Festival’s Horizons section, “Tatami” shows Iranian female judo fighter Leila (played by “The L Word: Generation Q” star Arienne Mandi) heading to the world championships with her coach Maryam (Ebrahimi). Soon, they receive an ultimatum: in order to avoid squaring off against an Israeli opponent, Leila should immediately fake an injury and drop out.
