Los Angeles cinematographer Tomas Koolhaas has unveiled the trailer to his highly anticipated film, REM. The documentary focuses on the work of Thomas’s father, the famed Dutch architect Rem Koolhaas. REM will explore Koolhaas’s buildings via a number of comprehensive camera angles, and the function and purposes of each architecture. So far REM has been funded by grants, and in order to see the film come to fruition, Koolhaas has launched a Kickstarter campaign to further raise funds. Watch the trailer above as a parkour athlete guides us through Rem’s Casa De Musica building in Porto, Portugal, and stay tuned for more on REM.
