Cal Ripken, Jr., who served as a consultant on the film, recalled in Sports Illustrated having lunch with Robert De Niro, with De Niro asking him about the Red Sox fans. Ripken also said it was a little creepy meeting De Niro at first, since when he did, the method actor was listening to an audio tape of Robert John Bardo, who stalked, and later murdered Rebecca Schaefer.
John Kruk, a longtime pro baseball player with San Diego and Philadelphia, was an extra in the film. He was critical of the production in several pre-release interviews, stating that while he liked Wesley Snipes, he couldn't swing a baseball bat in a remotely convincing way, and that Director Tony Scott knew nothing about baseball, and made no effort to learn (when Kruk pointed out to Scott that the film's presentation of rows of books in the dugout was totally ridiculous, Scott told him to go away and ignored it).
The San Francisco Giants' number 11 is retired (Carl Hubbell). But, recently Omar Visquel of the Chicago White Sox was given a retired number of (ironically) 11, which was worn by shortstop Luis Aparicio.
At the time of the film's production and release, it was speculated that Bobby Rayburn's portrayal as an African-American and playing for the San Francisco Giants was to draw parallels with Barry Bonds.
Wesley Snipes, John Leguizamo, and Robert De Niro appeared in movies dealing with men dressed in drag. Snipes and Leguizamo appeared in To Wong Foo Thanks For Everything, Julie Newmar (1995), and De Niro appeared in Flawless (1999).
When this movie was reviewed in Radio Times, as part of This Week's Top 10 Satellite Films Reviews By Adrian Turner, he wrote, "Director Tony Scott's film explores themes of baseball and stalking, but has little to say about either."
