Dando Shaft works in an ad agency where he comes up with the taglines we all remember decades later at the expense of any useful knowledge. He's unhappy in his job and embarks on a scheme to become "Everyman's Millionaire." He takes out a full-page ad in the NY Daily News for donations and he will live the life of a millionaire for your vicarious thrills. The endeavor is partly successful at best - money comes in, but not nearly as much as he'd like, and his affair with the trampy hotsy-totsy Bunny Fairchild destroys his marriage. Disillusioned and broke, he has to pull himself back up from rock bottom.
A great satire about 1960s suburbia, the frustrated people in it, and the American phenomenon of celebrity culture.
