Actors who are really good at being stuck somewhere?

It feels like watching a rite of passage, enabling the invigoration of the type of convicted self-reliance conducive to abandoning imposed constraints, cultivating the right mentality, embracing the unknown, exercising free will, developing an expressively personalized style while eschewing special effects and artifice, but really keeping it to the simple audience-character dynamic. Off the top of my head, Tom Hanks.
