Director Joon-ho Bong, the guy who brought us the awesome monster movie The Host (rent it today if you haven't seen it), has a new movie out: Mother. This one's not a monster or horror movie, but a thriller/drama about a mother desperately trying to free her son from prison. After her son is wrongly convicted of murder she goes on a frenzied quest to find the real killer. The trailer is great, and it's likely this movie will also be great. Check it out after the jump.
