According to Hollywood.com, Jackie and Jet had such an enjoyable time making The Forbidden Kingdom, that they want to make another film together and even have a script in mind.

Jackie said, “The first day we started filming, it felt like we had worked together for many years. After filming this movie, we didn’t have enough fun.”

Jet agreed, saying, “In four months we went from friends to becoming brothers.”

Apparently the two have been working on a script for about fifteen years and they are now seriously looking into making the film. They would not talk about the details of the plot, however.
