Rush Hour 4

[Haunt Master]

I heard that Jackie Chan will be back in this fourth film, but not so sure about Chris Tucker whether or not will he return to this film? It is set in Moscow. Sorry, I don't have link or any other informations here. I did check with IMDB.com - sorry, no information provided. Dang!

So, anyone ever heard about it or seen it somewhere online, please post it here. Thanks!!
