Steve Buscemi is an actor who does not really need to convince you that he is criminal through any sort of performance technique, he just naturally has that shady look about him. Well Buscemi does not toy with this in anyway for sure and fits together will the very well cast array of crooks in the film. Buscemi though has the right demeanor in his performance during the various flashbacks in the films that reveal what the men were doing before they went to the robbery. Buscemi even here carries the right relaxed approach that suggests Pink's calmer nature. How Buscemi does this though is portray Pink as a man rather relaxed in his circumstances who treats the upcoming proceedings as just a thing he does from day to day being a professional and all.
Buscemi is very good and even rather enjoyable by taking this approach in the flashbacks and does well not to oversell the more humorous lines he has. In his own monologue about his preference not to tip Buscemi plays it very to the point in a realistic fashion. In doing so he is very effectively setting up Pink as a naturally calculating sort, and looking at things too much is just his way of doing things. The same goes for when they are assigned the name and he is forced to take exception with the color choice given to him. Buscemi makes the reaction appropriately amusing by once again delivering it naturally as possible making basically the reaction that most men would have after being given the unfortunate name he is given.
His demeanor of course changes quite severely though once they make it to the warehouse after the botched robbery. Buscemi is extremely effective in bringing the needed intensity to the situation. He plays Pink very well by giving the right agitation as well volatility in his performance that sums of the feelings of man who does not know what's going on but wants to. Buscemi's best moments are when Pink reacts to the more extreme behavior by some of his cohorts. Buscemi's reactions are perfect in expressing the disbelief of the others, and reinforces always the fact that Pink is a professional above else. My favorite moment of his has to be his strained plea during the Mexican standoff that sums up how a sane man would view the insane situation quite nicely.
Buscemi's work is all together a solid work that adds to the film nicely and fulfills Pink's part of the dynamic of men incredibly well. I would not describe this as one of those supporting performances that steals the film though. He is indeed my favorite out of the cast, but that is not to say he always makes the strongest impression in every scene, I would say he makes the strongest in many scenes but not all. I don't want to sound like I am really criticizing Buscemi in anyway though as he handles the material just as he should, and really the only thing that really holds him back is the nature of the film. It's a very good performance by Buscemi although his best portrayal of a criminal would come as a less professional sort.
