Blade (1998)

>Ernest Dickerson was considered to direct before Stephen Norrington was hired.

>The studio wanted a campy spoof-like tone before writer David S. Goyer convinced them to make it dark and gritty.

>LL Cool J was approached for Blade before Wesley Snipes was hired. Denzel Washington and Laurence Fishburne were also considered. Snipes would originally star in a Black Panther movie

>Jet Li, Mark Wahlberg, Skeet Ulrich and Bruce Payne were considered for Deacon Frost before Stephen Dorff was cast.

>Patrick McGoohan and Jon Voight were considered for Abraham Whistler before Kris Kristofferson was cast.

>The movie was heavily reshot and reedited after disastrous test-screenings, and the original ending where Frost transforms into a blood monster was scrapped due to the poor CGI and replaced with a final swordfight between Blade and Frost.

>An alternative ending where Blade encounters Morbius to set up a sequel was shot but scrapped.
