 It was released on DVD in Fall 2010 by Oscilloscope Laboratories.Victoria Large wrote that "while "I Knew it Was You" works as a wonderful career retrospective for fans or a great primer for newcomers, the real power of the piece lies in the juxtaposition of the highlights of Cazale's career with the warm remembrances of his friends and the biographical facts of his life".Don R. Lewis of "Film Threat" felt that the film did not properly cover Cazale's early life, writing "From its awkward running time of 40 minutes to the way director Richard Shepard completely skims over the man's life outside of acting, I just didn't feel there was enough going on to make this doc truly special.
