When Mary was excised from the script, this created a small problem: Bryant should be saying that there are three remaining Replicants (Roy Batty, Pris, and Rachael), not four. Rather than re-shoot this scene, they rearranged the scenes during editing and put Deckard's confrontation with Leon after he bought his Tsing Tao, so that the four remaining Replicants would be Roy, Pris, Leon (not Mary), and Rachael. However, this created its own errors:
- In previous cuts of the film, when Deckard is buying his Tsing Tao and later talking to Bryant, he has a scrape on his face from his fight with Leon before it's even happened. (Fixed in The Final Cut.)
- Since he now buys his bottle before he fights Leon, it should be there while he's fighting Leon (it's not). The bottle mysteriously reappears when he gets back to his apartment. Considered a "beloved flaw" by Scott.
Mary was to be portrayed in the film by Stacey Nelkin, who originally auditioned as Pris.
