doing all the effects in 65mm at the beginning of the project as a means of maintaining image quality. Using a large format reduces the grain build-up, which is so often seen in other films, when special effects are added to a scene. Whenever a live action scene in Blade Runner was designed to have effects added to it later, it was shot in 65mm as were the miniatures. After one-third of the way through principal photography, Trumbull was called away to work on his own film Brainstorm (1983).
 

        When Blade Runner was released on the 25th of June, 1982 (Cinefantastique, p. 46) in America, and later in the United Kingdom and Europe, the special effects was one of the main criticisms of the film. The British trade publication “Screen International” wrote "the special effects dominate the film while the plot and characters fade into the background". Some critics believed that the level of violence in Blade Runner was more explicit than necessary. The United Kingdom and European versions of the film were more explicit than that released in America.
