Cohen said the film was significantly trimmed in post-production. Although he and
New World Pictures disagreed on the detail and pacing of the film, he agreed to increase the pacing of the film by removing some commercials and a romantic scene. Cohen did not believe the deleted scenes would work in the final product, but he called the process of removing scenes he favored "painful". Cohen said that executives at New World Pictures preferred a film that was strictly in the horror genre and had heavy amounts of gore, but
The Stuff seemed more satirical, humorous, and unconventional compared to other horror films. The comedic portrayals of the characters appeared to have "greatly diluted the horror element". He said that before the film was released, people in a different audience would favor this film instead of those in Cohen's target audience. The film premiered at USA Film Festival on March 30, and it was theatrically released in the United States by New World Pictures, opening in several California cities on June 14, 1985. The film did not perform well, and Cohen feels that it was hurt by the fact that it was sold as a horror film when it was basically a satirical comedy. Cohen stated, "the day
The Stuff opened in New York a hurricane hit and the newspapers were not delivered. Of course, we had received all these great reviews, but it didn't matter because nobody ever got to read a single word of them."
Copyright dispute The company Effects Associates was hired by Cohen to supply some of the special effects shots. When the shots were delivered, Cohen was not satisfied with shots of exploding factory buildings and paid only half (c. $8,000) of the agreed price for those shots. In
Effects Associates v. Cohen, Effects Associates brought an action against Cohen in court to claim full compensation, but also because the parties had no written copyright agreement regarding the use of the shots. The trial court decided in favor of Cohen, ruling that a grant was "implied" for the non-exclusive use of the shots in the film. At the
United States Court of Appeals for the Ninth Circuit in 1990, Cohen tried to say that under Section 204 of the Copyright Act, the transfer had to be written down, and this transfer was not in writing, but it did not apply to him. Judge
Alex Kozinski, the presiding judge of the Court of Appeals for the Ninth Circuit at the time, said: Section 204's writing requirement is not unduly burdensome; it necessitates neither protracted negotiations nor substantial expense. The rule is really quite simple: If the copyright holder agrees to transfer ownership to another party, that party must get the copyright holder to sign a piece of paper saying so. It doesn't have to be the Magna Charta; a one-line pro forma statement will do. and could allow other parties to use the footage. On September 20, 2011,
