Dylan Walsh plays decent men so steadily that you stop noticing him, which is both the point and the problem. As Sean McNamara in Nip/Tuck he made a careful surgeon worth watching for two seasons, and has spent the years since being reliable in other people's series.
Fi1m perspective
Every consultation in Nip/Tuck opens with the surgeon asking what the patient does not like about themselves. Julian McMahon's Christian Troy asks it the way a salesman asks about your budget. Dylan Walsh's Sean McNamara asks it as if he would rather not hear the answer, and then listens to the whole of it. That is Walsh's trade: the man at the desk who takes the question seriously while everyone else is working out what they can get for it.
He had been at this for some time before anyone paid much attention. There were small television parts in the late 1980s, then films: Loverboy (1989), Betsy's Wedding (1990), Nobody's Fool (1994) and Congo (1995), where he played Dr Peter Elliot in a large studio adventure. Then Ryan Murphy cast him in 2003, and for seven seasons and 100 episodes he was half of a Miami plastic surgery practice. Sean is the careful one, married to Julia (Joely Richardson), father to Matt (John Hensley), and so decent he is faintly tiring to be around. Walsh knows this and does not soften it.
What he does instead is let you see what the decency costs. Sean envies his partner, the money and the women and the ease, and Walsh shows it in the pauses, never in the lines. The pairing works because neither actor plays the villain, and McMahon returns the favour, letting Christian show, once or twice an episode, how much he would give to be trusted the way Sean is. For two seasons the writers keep the patients and the family in balance and the two men have something to play. From the third season on the show decides that outrage is plot, and by the fifth it has become the thing it set out to mock. We were cross for long stretches of it, and mostly on Walsh's behalf: he was still there, still doing the careful work, holding a straight face through storylines that no longer deserved it.
Since 2010 he has been reliable rather than surprising, which is not a small thing in series television. Four seasons as Al Burns in Unforgettable (2011–2016); guest and recurring work on Law & Order: SVU, Castle and Blue Bloods; General Sam Lane in Superman & Lois from 2021. Doctors, detectives, men with a title. The one lead in a cinema thriller, The Stepfather (2009), came out while Nip/Tuck was still running and did not change the direction of travel. His reputation remains tied to one part, and he has said plainly that he has no interest in playing a plastic surgeon again. On the evidence, the surgeon was the one part that gave his stillness something to push against. The procedurals ask him to be steady and he is; nobody has yet asked him to be envious.
