Solitary Man is a 2009 American film co-directed by Brian Koppelman and David Levien. The film stars Michael Douglas, Susan Sarandon, Jenna Fischer, Jesse Eisenberg, Mary-Louise Parker and Danny DeVito.

The film opens with 54 year-old Ben Kalmen (Michael Douglas), an attractive and very successful car dealer in the New York area, at his annual medical check-up; his doctor tells him he needs a CAT scan to get a better look at his heart, due to an 'irregularity' in his EKG.
