Lawrence’s potential involvement with this movie has been confirmed by multiple credible sources, while Farley’s... not so much. Still, as the story goes, Rush Hour was originally supposed to be about a “hapless white officer” who gets paired with a “smart-talking” Black one, leading to endless jokes about how white cops drive like this and Black cops drive like this. The biggest difference in this Jackie Chan-less version would have probably been “way less martial arts,” but Farley did have previous experience playing a master of ninjitsu, so who knows?
