Kropka is a scriptwriter for cinema, television, and animation that in recent years has been specializing in and writing about international animation. Since 2013, he has organized and curated various animation events around the world involving festivals so different and diverse as Etiuda & Anima, Stoptrik, Animateka, Animasivo among others. He has given diverse lectures about animation, also he was a member of the jury at the Animateka Festival in 2017.
In addition, he organized a small European distribution circuit for the Mexican Animasivo festival and other individual screenings in cultural centers, achieving that several festivals work together for the sake of the big passion that unites them all – animation.
It is perhaps this independent and outside-the-rules spirit that made him seriously consider founding ReAnima in Bergen, an improbable place for an outside-the-rules international animation festival. He believes that ReAnima is cultural and artistic way of helping to maintain a cohesive society but with new perspectives to understanding and conversing with the global environment in our times.
