Most underrated actor/actress?

Casey Affleck, Lena Headey

I speak of the pompatus of love.

Gary Oldman

Scott Wilson

How can Gary Oldman be "underrated"? I get the impression he is one of the most admired and sought-after actors in the biz, by critics, directors, and his fellow-actors.

A lot of my favorites there, Aldo. But the name "Sarah Bolger" was a new one to me. Having looked up her filmography, I see why. Nothing there has tempted me to view.

I did (sort of) watch "The Spiderwick Chronicles" (2008) (disappointing) and "Alex Rider: Operation Stormbreaker" (2006) (truly awful) with my son, but do not remember her at all. Which do you recommend for my conversion?

But the rest of your picks raise the tone of everything they are in, even if only in cameo roles.

Good Actor list. Ruffalo and Simmons my first thoughts. Would add Jim Caviezel.
