In a nutshell:

A group of ex Special Forces soldiers are brought together to steal a mysterious briefcase.

Quotes:

Spence: ‘You ever kill anyone?’
Sam: ‘I hurt someone’s feelings once.’

Vincent: ‘No questions. No answers. That’s the business we’re in. You just accept it and move on.’

Sam: ‘All good things come to those who wait.’

Sam: ‘Either you’re part of the problem or you’re part of the solution or you’re just part of the landscape.’

Synopsis:

Young IRA member Deirdre (Natasha McElhone) recruits a team of heist men to steal a briefcase. You don’t assemble a crack team of former special forces operatives unless the target is an extremely elusive one.

Enter Sam (Robert De Niro), Vincent (Jean Reno), Spence (Sean Bean), Gregor (Stellan Skarsgård) and Larry (Skipp Sudduth). Recruited to separate the mysterious briefcase from a heavily-guarded escort, there’s a permanent fog of distrust between the players, as their mission develops ever more complicated intrigues.

After a confrontation in Nice, the team acquire the case, only for true allegiances to be revealed, setting off a globe-trotting game of cat and mouse. The plot is as difficult to read as the poker-faced players, but the real joy from this one comes from the pulse-pounding spectacle.

Better on Blu-ray:

‘The car chases’

If you struggle to keep a handle on the plot, there’s no chance you’ll be lost during the movie’s stand out car chases, which shift up a gear with Blu-ray’s picture and sound clarity.

The first explosive chase sees the gang tearing through Nice, demonstrating how to take out your opponent by firing a rocket launcher from a moving car. The second will have you subconsciously reaching above your shoulder for a seatbelt, as De Niro and Reno’s Peugeot chases a BMW through the streets of Paris at breakneck speed. The authenticity of the chase makes it impossible to tear your eyes away, and on Blu-ray, the concentration (and consternation) on De Niro’s face is all the more apparent.

And if that’s not enough, the hi-def experience adds grizzled details to the mercenaries' craggy faces.
