Pirate Robot Improv Workshop

Tue, Feb 16, 2020, 7pm-10pm

Central European Time

via Zoom

EUR 45 per person incl. tax

There are two types of improvisers: the actor and the writer, the yin and the yang, the empathizer and the recognizer, the pirate and the robot. Riveting improvisational theater happens when actors unite both sets of abilities and use them as needed to create engaging, realistic, unusual, and hilarious performances.

Inspired by Billy Merritt and Will Hines' ground-breaking improv fable Pirate, Robot, Ninja, improv pirate Jeannie Ceglar (Pack Theater, UCB), joins improv robot Peter Graff in teaching this online workshop on the art of being a pirate or a robot whenever one is needed.

Peter is without a doubt the best improv teacher I ever had. I learned a lot and got to be part of a great community. The atmosphere of his workshops are very welcoming and judgement-free, I would recommend these workshops to anyone who's interested!
