What a lousy screenplay, man. If you watch carefully from the very beginning, Jackie Chan is actually the Executive Producer, his son is another producer, one of the female actors is also one of the screenplay writers. The scenario is ridiculous, about a invention of the artificial heart that can make half dead people resurrect from the dead. Lot of gun fights, explosions, demonic-like villains and globe trekkers. Since Jacki Chan has an Australian Passport and his wife a permanent resident there, he just like to use Australia as one the movie's shooting location other than Hong Kong.
This is a very childish and shallow action movie for the majority of video gaming generation, guys still live with their parents, eating instant ra-mien soaking in boiled hot water while still playing the video games. But if you really like Jackie Chan's movie, watch "The Foreigner" instead.
