 Hartman wrote a number of screenplays that were never produced. In 1986 he began writing a screenplay for a film titled Mr. Fix-It, and completed the final draft in 1991. Robert Zemeckis was signed to produce the film, with Gil Bettman hired to direct. Hartman called it "a sort of a merger of horror and comedy, like Beetlejuice and Throw Momma From the Train", adding, "It's an American nightmare about a family torn asunder. They live next to a toxic dump site, their water supply is poisoned, the mother and son go insane and try to murder each other, the father's face is torn off in a terrible disfiguring accident in the first act. It's heavy stuff, but it's got a good message and a positive, upbeat ending." Zemeckis could not secure studio backing, however, and the project collapsed. Another movie idea involving Hartman's Groundlings character Chick Hazard, Private Eye also fell through.
