The movie is called "Mr. Go 3-D", it's a Korean baseball movie and I've watched the trailer twice since I first saw it in my Twitter feed a little while ago. Here's the movie's synopsis:
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.
Three words: Bat swinging gorilla. Come on, that's gold.
And here is the trailer:
They really need to get this movie over here. I'd definitely watch it, with subtitles of course.
Hat tip to the great Jonah Keri.
