London -- Martial arts star Jackie Chan, who has turned down a chance to appear in the next "Rambo" movie, says he still hopes to act with Sylvester Stallone one day.

According to contactmusic.com, Chan and Stallone are good friends and they have promised each other to act together on the big screen some day.

Chan says: "I love Sylvester Stallone, we even used to be business partners. Although I haven't seen him in a while, I still hope to work with him someday. You know, the Chinese translation of Stallone includes the character for dragon, just like my name does. A lot of people would like to see a meeting of the dragons and maybe someday they will.

"So far we haven't found a script that works for both of us and our schedules for the past few years have been so hectic. Maybe someday we'll work together, but I don't think it will be 'Rambo 4'.

Chan wants to work with other Hollywood luminaries as well.

"There are a lot of other people that I'd love to work with as well. I think I would drop everything to be directed by Steven Spielberg in a film. I always wanted to work with the Scott brothers (Ridley and Tony) and I would love to act with Dustin Hoffman."
