Who do you think is the most underrated actor or actress?

Who do you think deserves more recognition from people for their
talent? Or who do you believe made a movie or show and doesn't get
enough credit for it?

I think Joseph Gordon-Levitt and Alan Ruck are very underrated. Joseph
Gordon-Levitt was AMAZING in 3rd Rock From the Sun, 500 Days of
Summer, and Inception, and doesn't get the credit he deserves. Alan
Ruck played Cameron Frye in Ferris Bueller's Day Off, and I believe he
stole the show, but people only recognize Matthew Broderick (Ferris),
Jeffrey Jones (Rooney), and Jennifer Grey (Jeanie) for that movie. Not
enough credit goes to Ruck.

So who do you think needs more recognition for their work?
