Sebastian Kellermann came into contact with 3D animation during an internship in 2009 at the age of 14. Since that day, animation became his passion. He pursued it as a hobby and later completed an apprenticeship as a media designer with a focus on 3D animation and postproduction after graduating from high school. During this time, he became increasingly aware of his fascination for animation in movies. So he started studying at ifs internationale filmschule köln and worked on an animated feature film as an animation intern for the first time in 2019. During his studies, he started to work part-time in an animation studio, which he then continued full-time after graduating from filmschool in 2021.
