The hunt is on for John McClane Jr. Earlier last month, we reported a shortlist of actors that were presumed to be vying for the role of Bruce Willis’s son in A Good Day to Die Hard, the fifth film in the franchise. Well today a new shortlist has popped up, and only one name on this new list was included on the old one: Breaking Bad’s Aaron Paul. Hit the jump to find out what other names are being considered for the role, and for a recap on what we know so far about A Good Day to Die Hard.So now Deadline reports that the search for Willis’ son is down to just four actors: Paul, Liam Hemsworth (The Hunger Games), James Badge Dale (The Pacific), and D.J. Cotrona (G.I. Joe: Retaliation). Hemsworth has become a bit of a staple on these studio shortlists as of late, as he’s also reportedly being considered for the Arthur role in Warner Bros.’ Arthur & Lancelot, as well as one of the male leads in Andrew Niccol’s adaptation of Twilight author Stephanie Meyer’s sci-fi novel The Host. He’s currently filming The Expendables 2, after which he has a number of projects to consider (including the aforementioned possible franchise-starters, and he’s also locked into the next three Hunger Games films).Hemsworth is actually the youngest actor on the list by a decade, as Paul is 32, Dale is 33, and Cotrona is 31. Paul’s a magnificent Emmy-winning actor, but the report cautions that his shooting schedule on the final season of Breaking Bad may conflict with the Die Hard schedule. Dale is a talented guy as well, but of the actors being considered he definitely looks the oldest. Then again, we don’t know exactly what the script calls for so he could be the perfect choice. Cotrona’s a bit of a newcomer, as he recently starred on the now-cancelled CBS series Detroit 1-8-7 and is poised to appear in the upcoming G.I. Joe sequel.Though I’m not familiar with Cotrona’s work, among the other choices there’s really not a bad pick in the bunch. John Moore (Max Payne) is set to direct the next chapter in the Die Hard franchise, which centers on Willis traveling to Russia to save his son, “but nothing is what it seems.” Beyond that, we really don’t know much else about the story. Moore’s involvement has me incredibly indifferent, but if they nab somebody like Paul or Dale, things could get interesting. Filming begins in January. A Good Day to Die Hard opens February 14th, 2013.
