Jackie Chan hasn't appeared in movies a lot recently, and Hollywood misses him greatly. Back in the 90s, he appeared in some of the great action movies of the decade, and when he merged his martial arts skills with comedy, it was a match made in heaven. He starred in Rush Hour with Chris Tucker, and the unlikely pair struck box office gold, and went on to make two sequels to the hit 1998 film. There are always rumors swirling around that Rush Hour 4 is in the works, and both actors would like to reprise their roles in a new installment in the action comedy series. However, nothing has been officially green-lit thus far.
