The Hunting Gun, an avant-garde piece of theater by Serge Lamothe, is a remarkably mesmerizing work, but it also presents challenges to a viewer: only one of its two performers speaks, and then it’s entirely in Japanese (there are surtitles in English). Adapted from a novel of the same name by Yasushi Inoue, the work begins with a prologue. An author, heard over a loudspeaker, recites a poem called Hunting Gun—written about a man with “a double-barreled Churchill.” The author subsequently received a letter from Josuke Misugi, who claims to be the man who inspired the poem. Out of the blue, he tells the author, he is sending him three letters in the hopes that he (or perhaps just someone, anyone) will understand his life.
