Directed by Ira Sachs, Passages follows the exploits of Tomas (Franz Rogowski), a filmmaker whose marriage to Martin (Ben Whishaw) is struggling. After his latest feature wraps, Tomas encounters Agathe (Adele Exarchopoulos), a stunning young schoolteacher that immediately charms him. After a night of passion together, Tomas finds himself eager to explore the potential of this new sexual relationship, sending shockwaves into his marriage. But when Martin begins to find love in the arms of another man, Tomas is the one who feels spurned and begins to re-pursue is husband. In this 1on1, we speak to Sachs about what it means to be happy and whether or not we can ever 'know' another person.
