Mister Buddwing is a 1966 American film drama starring James Garner, Jean Simmons, Suzanne Pleshette, Katharine Ross, and Angela Lansbury. Directed by Delbert Mann, the film depicts a well-dressed man who wakes up on a bench in Central Park with no idea who he is. He proceeds to wander around Manhattan desperately trying to figure out his own identity. He meets various women, played by Lansbury, Ross, Pleshette, and Simmons, and each woman triggers fragments of his deeply-buried memories.

Based on the 1964 novel Buddwing by Evan Hunter, the black-and-white drama was written by Dale Wasserman, and accompanied by a jazz-based musical score written by Kenyon Hopkins.

In his memoirs, Garner said "I'd summarize the plot but to this day I have no clue what it is. Worst picture I ever made. What were they thinking? What was I thinking?"
