Each member of Adam's social circle responds to his illness in a different way. This kind of character-driven film requires the very best from its ensemble, and all players nail their respective roles with naturalistic ease.
The sincerity of the acting sells the sentimentality. Each performance is sharply realized by a splendid cast. All actors bring something different to the table, resulting in a rich blend of diverse characters.
Perhaps the greatest compliment that can be said of the supporting players is that no one of them stands out. They're all doing precise and distinct character work that always hits the target without screaming for attention.
There's not a mediocre performance to be found in this movie. Every character is superbly played with authentic dimensionality, both through solo scenes and when interacting with each other. A perfect, organic ensemble performance.
Oldman and his tightly knit supporting cast (which includes the likes of Colin Firth, John Hurt, and Tom Hardy) give a collective performance that is quietly controlled, so as to keep the focus on the complex screenplay.
