By skyforbes David Leitch – His filmography involves Atomic Blonde, Deadpool 2, Hobbs and Shaw, Bullet Train, and The Fall Guy. All of which are fun action comedies, and I think he would of made a great director for the 4th film. Plus he's worked as a Stuntman before, so it would've be so cool to see him to see him interact with Jackie and Chris, and how they would work on these fight scenes and stunts.
Ilya Naishuller – his filmography involves Hardcore Henry, Nobody and Heads Of State. He would've been a decent choice to direct the film. I really like those films so I think he would of done a fun Rush Hour film.
Jonathan Eusebio – The only film he's directed is Love Hurts which wasn't good, but I think he would've good choice for Rush Hour 4. He did great action with Love Hurts, so I think his style would of worked of another Rush Hour.
out of all the directors, I would say David Leitch would've been perfect to direct Rush Hour 4. He's my favorite Action director right now, and I really liked what he did with Hobbs and Shaw, so this would been really cool to see!!
