I would love an anthology series. Completely use a different cast every season, with a different type of job, in a different part of the world.

The movie gave a sense that there's alot of these types of people out there, most are cold-hearted and psychopaths, but some are doing it to just get by. Some of them even make friendships.

"Why did you take this job?"

"My friend, I need the money."

Its almost like a subtle European version of Resevoir Dogs.
