Famed acting coach Jerzy Grotowski also used long hikes in the woods, as well as more eccentric activities, to help get actors out of their own way. There was the exploitation of errors exercise, where instead of stopping when actors messed up a line, they worked the error into their performance. If they mispronounced a word, they carried that mispronunciation through the rest of the play. There was the tiger exercise, where Grotowski chased the actors around like prey, goading them to roar like a tiger and get lost in the strange game of acting like an animal during rehearsal.
