There's evil Russians, Bruce Willis being Bruce Willis, half a famous catch phrase… and a new member of the McClane clan.

Watch the exclusive trailer below:

'Die Hard 4.0' introduced us to the cop's daughter, played by Mary Elizabeth Winstead (reprising her role here), but now we discover that he also had a son.

Much of the pre-publicity for 'A Good Day To Die Hard' focused on who would play John McLane Jr., (reffered to as Jack in the trailer) with Liam Hemsworth, Aaron Paul, James Badge Dale and D.J. Cotrona all at one stage vying for the part.

Eventually the studio picked Jai Courtney. He'll be familiar to 'Spartacus: Blood and Sand' fans for playing Varro, and will be seen in 'Jack Reacher' opposite Tom Cruise later this year.

Plot details for his character are scarce, but it seems like John Jr. has got himself into a spot of bother in Moscow, so dad has to help him out.

Naturally they blow up buildings, smash up cars and, for reasons not yet clear, ogle a biker girl taking her clothes off.

What do you make of the trailer? Do you think Jai Courtney makes a convincing son for McClane? Let us know below.

'A Good Day To Die hard' is due in UK cinemas on 14 February 2012.
