Another really good movie by Stephen Chow,
probably most likely will not come out anywhere other than China.
Anyways the movie is about a boy whose mom died and whose father works all day to make enough money to send him to Private school. His dad finds a ball which morphs into a super-dog alien thing and other !@#$% happens.
Just watch the movie its funny, sad, and has a great story. It almost made me cry :'(
IMDB anyways:
