Being John Malkovich

Craig, a puppeteer, takes a filing job in a low-ceilinged office in Manhattan. Although married to the slightly askew Lotte, he hits on a colleague, the sexually frank Maxine. She's bored but snaps awake when he finds a portal leading inside John Malkovich: for 15 minutes you see, hear, and feel whatever JM is doing, then you fall out by the New Jersey Turnpike. Maxine makes it commercial, selling trips for $200; also, she's more interested in Lotte than in Craig, but only when Lotte is inside JM. JM finds out what's going on and tries to stop it, but Craig sees the portal as his road to Maxine and to success as a puppeteer. Meanwhile, Lotte discovers others interested in the portal.

Being John Malkovich is a 1999 dramedy film written by Charlie Kaufman and directed by Spike Jonze. It stars John Cusack, Cameron Diaz, Catherine Keener, and John Malkovich, who plays a fictionalized version of himself. The plot brings to the forefront several issues in contemporary philosophy of mind, such as the nature of self and consciousness, the mind-body dichotomy, and sensory perception.
