A slip up gave some Xbox users an early Walking Dead surprise.

According to Deadline, The Walking Dead has its mid-season premiere on Sunday February 9, 2014 on AMC but the ninth episode of the series accidentally leaked free on Xbox Video Saturday morning. AMC confirmed the leak happened but would not divulge information on how the leak occurred. The Walking Dead was considered one of the most pirated shows on air for 2013.
