Chris Tucker holds up <strong><em>Rush Hour 3</em></strong>
Jackie Chan says Rush Hour 3 is stuck in neutral because co-star Chris Tucker is making too many demands.

"He wants too much power. The movie company hasn't obliged. He wants final editing rights and the final look at the movie and so on," Chan told The Associated Press Thursday.

Chan called Tucker a "good friend" but questioned whether he had the stature to be so demanding.

"He's still a new actor," Chan, 51, said. "How many movies has he made? Two movies have already made him very famous and made him a lot of money."

"He needs to learn slowly," he added.

A call by The Associated Press to Tucker's publicist, Samantha Mast, wasn't returned Friday.

While Rush Hour 3 remains in limbo, Chan said he's going ahead with another project - one with famed Chinese director Zhang Yimou. Zhang's recent films include House of Flying Daggers and Hero.

Chan declined to reveal details of the movie, saying only that it would be "galvanizing" and is set in the 1980s. He said the idea is his, but Zhang will work on the script.

"He relies on imagination ... like an arrow flying through water," said Chan. "He has elevated the martial arts genre. I believe he can make any type of movie now."
