Tobias Nölle returns to Berlinale Panorama with “Tristan Forever,” a hybrid portrait of a doctor’s decades-long fixation on remote Tristan da Cunha.

There's a melancholy to Tobias Nölle and Loran Bonnardot's Tristan Forever that is comforting. A lingering, existential question hangs over everything: where does one belong? In the film, a Parisian doctor (Bonnardot himself) decides to permanently move to the South Atlantic Ocean island Tristan da Cunha, one of the most remote places in the world.
