When their journeys ended, Abdullah settled in Chile, founding a successful film company and cinema, while Issa returned to Iran as something of a celebrity. There in Tehran, in an 18th-century Pahlavi palace, he built a museum to house all the artefacts that he and his brother had collected. It’s a place very much worth a visit (Omidvar Brothers Museum). It is the films, however, that are the most significant artefacts. At a moment in history when many want to end their country’s isolation, it seems appropriate to watch these two intrepid explorers embark on a journey that became a marathon celebration of how humanity can defeat its tendency towards fear of outsiders and foreigners. That, after all, is when travel is at its best.
