Michelle Monaghan has been cast in Ryan Murphy's sex drama Open. According to Deadline, Monaghan will play Grace, a successful gynecologist who's newly engaged to Scott Speedman's character. (Watch out, Mindy Lahiri! There's a new TV gyno in town.) She joins Wes Bentley, Jennifer Jason Leigh, and Anna Torv in a show that'll be Murphy's exploration of various facets of human sexuality. Monaghan is in the Matthew McConaughey–Woody Harrelson HBO mini-series True Detective, but Open would be her first real TV gig since Boston Legal.
