O.K. im not sure if this is considered a big or real slip up but check this out, alright midway in the movie when jack and wang are in the wheelchairs in lopans room after lopan enters he begins to talk to them listen,when he says "all i need is a women with dragon green eyes to make me old again, young again" now the slip up occurs when he says "old again" then immediately corrects himself saying "young again" knowing he messed up his lines but no one seemed to have cared if it made it into the final movie. Pretty

funny though
