Endgames Improv does stuff. Also, they do it well. They’ve been doing it well for years and the city of San Francisco is made better by their exploits. On Friday, April 12, 2013, the group, known for divergent decisions and experimentation, presented Mute Defiance at the Stage Werx theater, a handsome, twilit proscenium. Improv actors set to challenge television by assimilating, by becoming one, by layering live intonations against projected programming, utilizing Netflix, the ubiquitous, quirky, dorky hamlet of entertainment, resulting in post-production puppetry.
