So far we've learned that Die Hard 5 is going to be called A Good Day to Die Hard, Bruce Willis is back as John McClane, and plot details include McClane going to Russia to save his son, who it turns out is somehow embroiled in a terrorist plot. The instant the words 'John McClane's son' were glimpsed in Twentieth Century Fox's synopsis, the Internet exploded with the obvious question of which young actor is worthy enough to play Bruce Willis' onscreen progeny?

Today we have that answer - but do you agree with the studio's pick?

Last we heard, names like Ben Foster, Aaron Paul and Liam Hemsworth were being tossed around for the role of John McClane Jr. - and according to the reader responses, each of those actors had their pros and cons. As it turns out, it was all wasted debate: the part of John McClane Jr. has gone to Jai Courtney (pictured above doing a screen test with Willis).

Fox made the announcement today, along with a rundown of Courtney's achievements in acting - in case, you know, you have no idea who this guy is. The Australian actor played Varro in Spartacus: Blood and Sand, has a starring role in the upcoming Tom Cruise film One Shot, and got his start on Australian TV and in theater (the latter of which he won awards for). Between Jai Courtney, Sam Worthington (Avatar, Wrath of the Titans), and the brothers Hemsworth (Thor star Chris and Hunger Games star Liam), it seems we have an official Aussie leading man invasion on our hands right now. Ace!

Not having seen Courtney in much, there's not a lot to say about him - except that it's going to be a little awkward seeing aging action legend Bruce Willis having to stand next to this guy:

Of course, the real question is: Does Courtney have the potential to carry a hit action franchise into future installments without Willis? If Bruce has proven anything, it's that muscles don't count as much as swagger when it comes to being badass.

A Good Day to Die Hard will be in theaters on February 14, 2013.
