Black Rain (1989)

Continuity mistake: During the big fight scene at the end of the movie, both Nick and Sato become totally saturated and covered in mud. Nick defeats Sato, and is shown to have immediately arrested Sato and brought him to the police station. It is clear they came directly to the station from the fight, yet there is now hardly any mud on either of them.

Continuity mistake: When they fly to Osaka they leave on a 747 and arrive in a DC-10.

Revealing mistake: Watch Andy Garcia's decapitation scene. His head starts to come off before the sword makes contact with his neck. Slow motion helps but is not required.

Trivia: A great deal of the film was actually shot in Japan, and it was reportedly very difficult on the cast and crew. The cost to film in Japan was very high, and the shoot was highly restricted, causing frequent issues. The original cinematographer even left production because he became too frustrated by the experience. Filming was eventually moved to the US to combat these issues.

Trivia: Jackie Chan reportedly turned down the role of one of the villains in the film, as he felt audiences wouldn't want to see him play a bad-guy.

Trivia: Was Ridley Scott's first successful film in a decade. Every other film he had made since 1979's "Alien" flopped at the box office, while "Black Rain" ended up becoming a massive hit. It was the eleventh highest-grossing film of the year.
