Little Rock’s Mary Steenburgen has announced that she’ll be joining the third season of “Orange is the New Black,” playing the mother of irredeemable crooked prison guard George “Pornstache” Mendez, pictured above. It’s been a great year for the Newport native, who stole the show in “Last Vegas” (presumably? I somehow missed “Last Vegas”) and was pretty menacing in her three episodes of the most recent season of “Justified.” In other news, “Back to the Future III” is still not on Netflix (expect regular updates on this front).
