Four extraordinary artists — an older couple moving toward the end, a younger couple chronicling the journey — come together to make ”Two Strangers Trying Not To Kill Each Other.” Filmmakers Jacob Perlmutter and Manon Ouimet spent a year living with world famous photographer Joel Meyerowitz and his wife writer Maggie Barrett, resulting in an exquisite cinéma vérité of tremendous depth and intimacy. The filmmakers spoke from their London home about their “soulful collaboration,” small light camera gear, large emotional gains, and of course, distribution. Quite a journey.
