Everybody is identical in their secret unspoken belief that way deep down they are different from everybody else, wrote David Foster Wallace in his influential 1996 book “Infinite Jest.” Shortly after reading that 1,079-page tome, Rolling Stone reporter David Lipsky set out on assignment to travel with the newfound celebrity author on the last five days of his book tour, to try and uncover what made the prolific and conflicted writer tick. Based on the memoir that Lipsky wrote after Wallace’s death, the film can be seen as a profoundly compelling exploration of the relationship between two writers, but it’s also a story of universal truths—the art of talking, the high of a good conversation, and the simple pleasures of meaningful connection. Jesse Eisenberg is wise and wonderful as Lipsky, while Jason Segel is quietly devastating in his heartbreaking take on Wallace. Full of humor and melancholy, life and loneliness, director James Ponsoldt (“The Spectacular Now,” TCFF 2013) handles the outpouring of beautifully alive emotion with skill and tenderness.
