- The original title was Tom Boy: Revenger’s Tale and then changed to The Assignment.
- It was changed for commercial reasons beyond Hill's control, but he notes that Tomboy is not considered politically correct, e. g. in America.
Walter Hill shed some light on it in a 2017 interview with Ryan T. Cusick for iHorror.com:
RTC: I read that the name of the film was originally Tom Boy: Revenger’s Tale before it became The Assignment. Do you believe that is going to have an adverse effect on your film?
WH: Changing the title?
WH: Well I don’t know. That is kind of unknowable, isn’t it? If you ask me did I prefer the original title?, I did, but these are commercial things that have to do with distribution, etc. The movie in England is called Tomboy, in France, it is called The Revenger, the graphic novel in France is called Body and Soul. I don’t know about other countries, so it is a film right now with many titles. It was made under the title Tomboy: Revenger’s Tale so in my head, it is still kind of that. But they seemed very pleased with The Assignment, so “you role [sic] with the punches” and you…what is the other one since I am dealing with clichés here?
WH: Well I am not going to try and run away from it, it’s not my style. You know the word Tomboy is felt to be politically incorrect in certain circles I think that is pretty limiting. At the same time, you don’t want a title that is going to go out there and offend people.
WH: In the time between when the script was written, and the film was shot, and now, somehow the word [Tomboy] had slipped into disrepute in America, it is not in England. [...]
An explanation of why Tomboy may no longer be considered politically correct from Elizabeth King's 2017 A Short History of the Tomboy in The Atlantic:
Today, the increasing visibility of genderqueer and trans people—along with the increasingly flexible nature of gender presentation and discourse about it more generally—further complicates the idea of tomboys. Some feel that “tomboy” is no longer a useful term, given that girls and women are progressively more free to explore their gender expression beyond traditional femininity. If culture’s understanding of girlhood is not exclusive to being “girly,” is a tomboy a tomboy anymore, or just one way of being a kid?
