There are some television performances that come like fireworks. Others have a more gradual introduction: an unobtrusive presence on the periphery, a reading line that recodes the scene, a recurring figure who comes to be the moral weather on the show.
Supporting actors are likely to work with the most sensitive work and scarcest space. They construct the social ecosystem upon the leads, which makes the plot a place inhabited. Awards organizations sometimes see it, there has even been a long-standing Golden Globe supporting-actor award on television, but the actual test is easier: take the performance out, and the pulse of the show is different.
These are the ones that viewers will recall, even at the time when they cannot locate the name instantly.

1. Ann Dowd
The superpower of Ann Dowd is the extent to which she can appear ordinary just long enough. That placid surface, accessible, church-basement familiar, makes it even more high-stakes as her characters display their more acute instincts. In ensemble television, even that power is made structural: she can make a scene feel safe, and then sour it. The presence of Dowd also makes the world of a show more realistic in a psychological sense since her characters are carried with an uncomfortable implication of menace coming in a polite way.

2. Stephen Root
Stephen Root possesses that elasticity of character-actor that allows a show to change tones without breaking. He can be the odd little motor that makes a B-story run in comedy, or a pressure point, all friendly until it is not, in darker content. The talent of the gifted, Root, is specificity: the voice, the posture, the manner in which he follows through with the internal reasoning of a character. Root can afford to be weirder in a series where he is already orbiting the Sun, as he makes it seem as though it is a neighborhood to live in.

3. Margo Martindale
Margo Martindale comes onto the screen already with back story. The viewers feel history in her silence, in the effectiveness of her responses, in her refusal to beg attention to her. And this is exactly why she defines shows asides: she makes the world bigger than the one that the main character has. Her characters, even when not directly featured, are hauntingly lingering like the second plot running parallel to the main one.

4. John Carroll Lynch
John Carroll Lynch is like an everyman until the writing demands that something stranger and he just becomes it, as though that darkness had been present in the ordinary all along. That plastics qualifies him as a stabilizer of the series: he is able to act decently without being cornball, to threat without histricks. When he is the one casting authority, the viewers think it is true; when he is the one casting its fault, they think that is as well. In any case, the show gets weight.

5. Becky Ann Baker
Becky Ann Baker is better at the TV character who is most easily flattened the parent. She does not use the cardboard version as she gives her characters joyful contradictions-warmth with conditions, humor that can be offensive, love that is not necessarily soft. That really texture is important due to the fact that the family is used to making sense of the decisions of a lead through its dynamics rather than any monologue. The dynamics in the work by Baker are stingy enough.

6. Patrick Fischler
Patrick Fischler can change the temperature of a scene in a blink of his eye- open and pleading, or suddenly on the defensive, or strangely alert. That is invaluable in serial storytelling, since he is capable of dropping such doubt without declaring it, setting paranoia without the need of a twist. Another way of saying that Fischler makes a show feel real is his characters seem like people who have an offscreen life with which they are actively concealing.

7. Loretta Devine
Loretta Devine is the type of presence-grounded authority that does not require amplification. She is able to play romanticism without losing momentum and cruel love without losing the human-side, which is an emotional juggling act that many series are banking on, particularly when their protagonists get out of control. The presence of Devine can instantly enlarge the scope of compassion of a scene, transforming a plot point into something resembling care, grief or endurance.

8. Bill Camp
Bill Camp frequently appears as a man who has access, professional power, institutional power, community position, but never as a clean badge. His acting has the viewer deciding, on a moment to moment basis, whether they are witnessing ability, threat, or fatigue. That vagueness is no silver, it’s structure. Camp brings systems to life with people instead of symbols, and this is what makes long-running drama gritty.

9. Vella Lovell
Vella Lovell specializes in the nervous, overachieving contemporary workhorter: someone who attempts to act cool while inside the car, racing away as their heart races. That dynamism is slowly becoming the trademark of comedy since it provides tension without sadism. The characters of Lovell frequently serve the role of tonal translator of the show, or someone who reacts in the manner of a real person to the ridiculous situation, to allow the audience to continue laughing, without drifting out of the action.

10. Ken Marino
Ken Marino is not embarrassed but committed to desperation and that is all the difference. In ensemble comedy, he becomes the person whose attempt to do something right turns into a punchline to itself, making more attempts, making them grander, letting himself be taught less effectively. Every generation of comedies featuring Marino can create whole ecosystems of comedy of sincerity gone wrong, since he makes misfortune not smug but earnest.
Sometimes supporting actors do not even see their faces on the billboard, yet what they do is what is rewatched by the viewers. They possess the tonal line, and sharpen the posts, and give leads to one to argue with, lean on, or to fear.
When these performers click into rhythm of a show, the series does not only become better, it gets a spine.
