Will Smith as J and Josh Brolin as young K in Men in Black 3

Two intriguing new images from forthcoming sci-fi action comedy Men in Black 3 are now in the public domain. The movie, due for release in the UK on 25 May 2012, follows agent J (Will Smith) as he travels back in time to prevent the death of his friend and mentor, K (Tommy Lee Jones).

Josh Brolin plays the younger K - marking the third film in which he’s appeared alongside Jones, having previously starred in Coen brothers’ thriller No Country for Old Men and crime drama In the Valley of Elah. In the first image, Brolin can be seen sitting next to Smith on a suitably futuristic-looking contraption.

The second picture sees Smith and Jones back-to-back, guns drawn – though the only danger they appear to be in is from the over-zealous set designer who decorated the restaurant. J has clearly graduated from the noisy cricket, but it looks like even after all this time, K still packs the bigger weapon. Tommy Lee Jones as K and Will Smith as J in Men in Black 3
