Kevin Smith promised to unveil the first trailer for his latest horror film Tusk at San Diego Comic-Con, and he delivered this evening. And its much weirder than even we expected. Starring Justin Long as a podcaster visiting Canada for a new story, Longs journey takes a turn when he meets an old man who… winds up surgically turning him into a walrus. Its as bizarre as all that sounds, and Smith looks like hes blending body horror with a really strange sense of humor in this movie. Well just have to see what comes of it when it hits theaters on September 19th.
