20 000 Jews Under the Sea was created as a time limited group for research with a goal to establish how can be the space part of acting improvisation show for the Academy of Performing Arts in Prague. In the end of the research, we have decided to continue as a group and play in front of the public because we found great synergy and share the same sense of humor! Our group is formed by improvisers with long experience (from 6 to 12 years of practice), students of acting at the Department of alternative and puppet theater, students of music conservatory and one Bulgarian.
