Koos van Staveren is the owner of the garage Garvak where they shot the movie. In January 2017 the movie became reality according to the news. Koos van Staveren is diagnosed with cancer and his garage is threatened by bankruptcy. Instead of running a marathon, the makers and cast of The Marathon organized a benefit evening on January 5 to raise money for Koos van Staveren. They raised almost 9500 euro for the garage.
