(Fist Fight is an Ice Cube starrer without any widely known/advertised buddy or ensemble, its not targeted to AFRAM audiences, is not a franchise, and there are no other factors that would add or take away from the box office other than this movie seems to be about bullying (among teachers) in Highschool which is a topic that I think would take a little away from the box office (bullying is no longer cool... even in movies).
Ice Cube is a $15 opener.
Add/subtract if:
placed in an ensemble or partnered with a buddy +5 = 20
in an African-American targeted movie -5 = 10
placed in a tentpole franchise film +10 = 25
