In 2000, at 56 years old, Dutch architect Rem Koolhaas (b.1944) was awarded the Pritzker Architecture Prize, the most acknowledged international award recognizing a career of achievement in the art of architecture. Having been one of the founders of the architectural form ‘Office for Metropolitan Architecture’ (OMA), in 1975, OMA maintains, currently, offices in Rotterdam, New York, Beijing, Hong Kong, and Doha. This global presence worldwide is fully in tune with Koolhaas’ initial instinct of what architecture should be: a constant exploration. Koolhaas, who was once a journalist (and maybe still is), and could be said to embody ‘the architect explorer’. Koolhaas’ thought-process about his perception of the world and about architecture, is shown to us in a cinematic style that, intentionally, seems to move and ﬂow, most of the times to the sound of the architect’s own words but also to the sound of the words of others who closely interact with him or with his work. These intertwined with images of Koolhaas’ creations and daily life, which conveys a sense of warmth and intimacy to the documentary, refreshingly surprising. REM is a unique opportunity to get an inside view of the ideas that drive Koolhaas’ work, one of the most acknowledged contemporary architects worldwide.
