Korean. Baseball. Gorilla. Movie.

I think the title of this post just about says all you need to know about MR. GO, but if the words "Korean. Baseball. Gorilla. Movie." don't have you dying with anticipation you need to read the synopsis at YouTube:

Wei Wei grew up in the circus with a bat-swinging gorilla named Ling Ling. After her grandfather dies in the Great Sichuan Earthquake, she has only Ling Ling to depend on. In order to pay her grandfather's debt, she has no choice but to accept sports agent Sung's proposal to bring Ling Ling to the Korean Baseball League. Despite serious doubts and ridicule from the league, Ling Ling, now dubbed 'MR. GO', becomes an instant hit, hitting one home run after another and propelling his floundering team to the playoffs. However, the rise to stardom is met with unexpected troubles and MR. GO must now face adversaries beyond his control.
