Fringe star Anna Torv and Jennifer Jason Leigh, coming off Revenge, have have joined the cast of Open, HBO’s drama pilot from Ryan Murphy. The Fox 21 project, which Murphy co-wrote with Lauren Gussis, is described as a modern, provocative exploration of human sexuality and relationships. In her followup toFringe, Torv will play one of the five central characters, Windsor, a yoga instructor in a longterm relationship with Holly (Leigh), an actress intensely committed to her career, who, upon meeting Grace, feels an instant connection. Aussie Torv, repped by WME and Australia’s United Management, and Leigh, repped by CAA and Untitled, join previously cast Scott Speedman and Wes Bentley.
