"For the last seven years, we've been turning down the script, turning down the script. Yesterday, we just agreed. The script probably at the end of this month will have a second draft, and next year, probably [we will] start, I hope, if Chris Tucker agrees. It's not about money. It's about time to make [it]. We're all, like, old men. I told Chris Tucker, 'Before we get old, please, let's do Rush Hour 4."
Jackie Chan had that to say on the possibility of Rush Hour 4. So it looks like the framework is already in place for Lee and Carter to go off on yet another adventure. Jackie Chan is interested in making it happen, and a script worthy of his return is on the verge of being turned in for a second draft. Now it's really just a matter of getting Chris Tucker to agree to come back to the series, and then they will be good to go.
