Though HBO opted not to move forward with his sexual drama series Open, the Ryan Murphy empire is continuing to expand regardless. FX has given a straight-to-series order for a companion series to Murphy’s wildly popular horror anthology American Horror Story. This new show, American Crime Story, will apply the anthology conceit to some of the biggest true crime stories in history, and the first season will start things off with a bang. The 10-episode first season of ACS will be called American Crime Story: The People Vs. O.J. Simpson. More after the jump.
