Trivia

Christopher Reeve had the script in his possession for a long time, before he agreed to make it. Reeve had read a few pages, and felt it wasn't for him, before dumping the script on a pile of other screenplays in his bedroom. A few weeks later, he picked it up and decided to try again, and instantly liked the script. He made the material his next project.

Morgan Freeman garnered an Oscar® nomination and was one of the rare Cannon Films which would receive this rare achievement along with Jon Voight and Eric Roberts in El tren del escape (1985).

The Cannon Group, Inc. agreed to finance this film as a pet project of Christopher Reeve, on the condition that he appear in at least one more Superman film, to which they had recently acquired the rights. The result was this, and Superman IV, en busca de la paz (1987).

One of the locations used was the old Seville Theater, in a rundown section of St. Catherine Street, near the old Montreal Forum. By that time, the theater had been closed for quite a while, and they redressed it as an adult movie theater on New York City's 42nd Street, leaving many to believe that the Seville Theater was being turned in a porno palace. After filming was done, everything was taken down, and the theater remained closed, but was basically a shell, as the owners let it fall into disrepair. Although the city deemed the front of the building "historically important architecture", the whole structure was ultimately demolished in 2010.

Director Jerry Schatzberg and Christopher Reeve wanted to shoot the film in New York City, where it is set, but The Cannon Group, Inc. insisted the picture be shot in Montreal, Quebec. The move ended up saving the movie between $1-2 million.
