Diederick started his career as a junior copywriter and quickly became one of the best Dutch ad men and together with Simon Neefjes and Cor den Boer co-owner of the biggest agency in The Netherlands, TBWA\Neboko. He created the commercial Elephant for Rolo (which won a Grand Prix for Film in Cannes and was voted best Dutch ad of all times), as well as the legendary campaigns Biertje? for Heineken and supermarket manager Harry Piekema for Albert Heijn, which ran for twelve years. 30-40 films for these last two brands were executed by hazazaH. Diederick has been indicted in the Hall of Fame of the Art Directors Club Nederland and was named Legend by the Dutch Association of Agencies.
Ten years ago Diederick decided to turn his creative life upside down and fully focus on directing film. Not ‘only’ commercials, but feature length films – talking about a giant leap. After a few years of preparation (Diederick literally vanished from ad land) he debuted with the movie ‘The Marathon’ which won a prestigious Golden Calf from the audience at The Netherlands Film Festival. A few years later Diederick directed the biopic Blood, Sweat and Tears about the extremely popular, late singer André Hazes. The film won 3 Golden Calves.
In that later period Diederick occasionally started to work as a creative again. And at this time he writes scripts and directs more and more commercials with his company Stories & Pictures for brands like G-Star Raw Worldwide, Remia and Radio 538.
Besides being part of the hazazaH clan, the genius copywriter, scriptwriter, creative director and – most of all – commercial director will continue to make feature films: ‘The process of making feature films takes years. I like being on a set and writing scripts more often. Creating commercials keeps me in shape, sharp and fresh. As an ad man – which I still am as well – I simply love doing it. It’s as simple as that.’
