This movie featured over twice as many stuntmen as it did actors and actresses. It set the world record for the biggest ratio of stuntmen to actors and actresses. Reportedly, over eighty stuntmen worked on this movie.
According to the book "Clint Eastwood A Cultural Production" by Paul Smith, during the early stages of principal photography, Charlie Sheen had substance abuse problems.
In an article titled "Rookie Stunts, Effects Dazzle Viewer" published in the January 1991 edition of "American Cinematographer", special effects supervisor John Frazier said of this movie, "You know, things went really well, but you have to give credit to everyone involved. Clint Eastwood and (production manager) David Valdes really gave us the time and their confidence to do it right. We were never really rushed, which is so important. We were able to do every one of the major shots in one take: the car out of the building, the carrier turning over, and the planes colliding. That says something. These guys respect the crew and every job being done. It makes a big difference."
This movie is widely considered to have, as Dave Kehr of the Chicago Tribune put it, arguably the "most spectacular action sequences (Clint) Eastwood has ever filmed."
This movie was to be directed by Craig R. Baxley starring Matthew Modine and Gene Hackman in 1988, but the production was stopped by the Screen Actors Guild strike.
