* WhatCouldHaveBeen:
** Creator/ShaneBlack claims his initial script was much darker, and more graphic. Amongst the many differences, it included some alternate action sequences, and more violence, like the scene where Mitch and Charly are captured and get tortured. Both characters also had bigger backstories in the original script, Mitch, at one point, tells Charly how he was gang raped in prison, and how his wife refuses to let him see his son, because of what happened to him, and Charly also had more of a dark backstory in the script, than in the film.
** The big turn would have been [[spoiler: Mitch dying in the final battle, with a DyingDeclarationOfLove to Charly. As part of a deal to keep this all quiet, Charly would have had federal agents tell Mitch's ex-wife that another man (Timothy) had committed the crime he went to jail for, earning Mitch a posthumous pardon and a big settlement for his family]].
** Originally the name "Sam Caine" was simply a name her brain threw up as an anagram for "amnesiac". In the finished film it's her former alias.
** The 100-year-old Windermere House in Muskoka was a planned filming location, but it burned to the ground before the scenes had been finished.
** Studio executives considered rewriting the film to have a male lead, with Creator/StevenSeagal or Creator/SylvesterStallone in mind.
** The ice skating scene was scripted to have Samantha perform a double axel flip and shoot from under her upside down head. After testing it out on location and with green screen, they dropped it from the film.
** Creator/CraigFerguson auditioned for the role of Timothy.
