The plot is being kept under wraps for the time being. While a draft of the screenplay seems to have been met with approval from the actor, it still needs to be tweaked before production can begin. Bruce Willis had this to say:
Not much else is known about Die Hard 5 at this time, and its unclear if Len Wiseman, who directed Live Free or Die Hard, will return. Bruce Willis has stated in the past that he'd like both Len Wiseman and Justin Long to come back for the sequel. At this year's Comic-Con, the action star did not rule out Kevin Smith as a director in the odd change that Len Wiseman decided not to return.
A Good Day to Die Hard was released February 14th, 2013 and stars Bruce Willis, Mary Elizabeth Winstead, Jai Courtney, Yuliya Snigir, Patrick Stewart, Megalyn Echikunwoke, Cole Hauser, Anne Vyalitsyna. The film is directed by John Moore.
