Deadline reports that Oscar nominated Glenn Close will be joining the cast of Guardians of the Galaxy in some kind of leadership role in the Nova Corps. Likely she will be the Nova Prime but there is no known female Nova Prime (that I know of) in the comics so likely she will be a new character.
Glenn Close has made a habit of playing strong women who you don’t want to mess with so she is a perfect fit to be the Nova Corps’ version of Nick Fury. The real question is will she take an active role in the action or, like Fury in the Avengers, be more behind the scenes and giving orders.
Either way, great addition to the film.
