Leonardo DiCaprio launched his own personal YouTube page to host the first trailer for his upcoming shoot-em-up, "One Battle After Another." The film, directed by Paul Thomas Anderson, stars DiCaprio as Bob Ferguson, who was once part of a black ops unit called "The French 75." His daughter is seemingly kidnapped, prompting a mad scramble to rescue her. The movie also stars Teyana Taylor, Regina Hall, Chase Infiniti, Benicio Del Toro and Sean Penn, and hits theaters September 26. See the trailer (CAREFUL! NSFW LANGUAGE!) here.
