Was filmed with the title "Seven Year Storm" and publicized in several trade magazines with that name. Warner Bros. decided to re title the finished pic "Hard to Kill" to make it sound more like a slam-bang action film.
Warner Bros. demanded for movie to be heavily cut and re-edited down to 90 minutes long running time in order to be more straightforward and fast paced movie and to have more theatrical screenings. Same type of re-editing also happened to other Steven Seagal movies that he made for Warner Bros. Some scenes were cut while some others, including parts of the plot, were deleted, which is why movie suffers from bad editing in certain parts. Some of the scenes which were deleted during re-editing are; Original opening scene between Storm and his wife and son, Trent's men interrogate and kill Andy's black nurse friend, longer deleted part of the movie where Storm's son Sonny is kidnapped by Trent's men but manages to escape, O'Malley's funeral scene, and more dialogue between characters in many other scenes. Reportedly, alternate ending was also filmed where Storm kills Trent and says "Take that to the bank". Storm is shown saying this line in theatrical trailer, which indicates that there indeed was alternate ending where Trent dies.
Theatrical trailer shows three deleted scenes; Trent saying "He's toast, do you understand" to his men, Storm saying "Take that to the bank" line (after he kills Trent in alternate ending) and parts of original ending which had Storm, Andy and Sonny at a funeral for O'Malley.
Steven Seagal did not get along with Bruce Malmuth and considered him to be a very poor director, stating in a 1990 interview "I think it's a miracle that this guy can put one foot in front of the other." Chief among Seagal's complaints included dissatisfaction with filming the action scenes and being excluded from the editing process.
One of three Steven Seagal movies released within a year of each other, the other two being Above the Law (1988) and Marked for Death (1990). All movies have three words in its title and Seagal playing a police officer
