Willem Dafoe played a counterfeiter in To Live and Die in L.A., and one extended scene showed him at work. He was very sure-handed in pouring gunk on the plates, operating the complicated machinery, picking up the right tool without hesitation, etc. It wasn't done all in one shot like Clooney's scene, because the process takes hours, maybe days. Dafoe wasn't casual, but he wasn't finicky either. He just looked like a man who had been doing the job for years.
