Jackie Chan and Chris Tucker have always said yes but nothing has come out of it for all this time, then again RH3 was similar and only happened randomly so anything is possible.
I would like to see it, counting that the Shanghai series is getting its third film maybe we will see a revival of more American Jackie Chan projects. Rush Hour is likely his most popular mainstream american film and since the TV project died after one season they might want to try a go at the film franchise again.
I love the first film and never liked the second, the third one being ok but I would need to re-watch them all. I also love that the film series is named Rush Hour and the only reference is a piece of dialog that has no baring in the plot or anything whatsoever
Rush Hour 2 was my first DVD, I remember it felt so "futuristic" to own it with its animated menus and what not.
