He has published a number of books, of which the best remembered is his The Golden Turkey Awards, which appeared in 1980, which he co-wrote with his younger brother Harry Medved. This book was pivotal in calling the public's attention to the humorous potential of bad movies; its selection of Plan 9 from Outer Space as the worst movie ever made helped turn that almost forgotten Ed Wood film into a cult film. This book spawned several sequels.
He is one of the Jewish voices in America praising Mel Gibson's controversial movie, The Passion (another is Steven Waldman; see ). Medved reviewed a pre-release version of and called it "the best adaptation of The Bible in Hollywood history".
