I haven't watched enough BSG to agree with Olmos. I do like Tony Shalhoub, and not because he does Monk. I don't know if I can agree with Doogie Howser just yet, even though, "Suit up!" (from How I met your Mother) is one of my favorite things to say. Linda was good in Liberty Stands Still.

Tony Shalhoub was brilliant in The Siege-- a highly underrated movie! And as for Neil Patrick Harris, I could say he was great in Starship Troopers (another deeply underrated movie), but really-- Harold and Kumar Go To White Castle! Come on, that was awesome! And for Linda, I gotta say Dogma!

Jenna Jameson.... hands down

Starship Troopers, while not my favorite movie, does get credit. The commercials/propaganda videos throughout the movie made it interesting like I was part of that time.

Shalhoub always seems to pop up in various movies with little roles, and each one is something different and to the point, which was why I like him.

I really don't know what to say about Dogma. It is just one of those movies. I'll laugh at it, I might watch a couple minutes of it if it happens to be on the tube, but I sat through it once and that was enough for me.

Jim Carey is the best actor of our time. He should have at least three Oscars; Man On The Moon, Eternal Sunshine of the Spotless Mind and The Truman Show. He has created two of the funniest characters of all time in Ace Ventura and the Mask. His roles in Limony Snikets, The Grinch and Horton Hears a Who will make those movies classics for young people and those young at hart to watch generation after generation.

Some of those old time character actors were really good. My favorite is Fujiwara Kamatari, who was in just about every PCL/Toho movie from 1933 to 1965, and quite a few after that. He had a sly and idiosyncratic manner of speaking which made him quite funny. You can see him in a bunch of Kurosawa movies, but i don't think he was well suited to Kurosawa, who wanted over-the-top emotion. (Mifune is much better in non-Kurosawa films.) Fujiwara was the lead in "Tabi yakusha" (Travelling actors) 1940, where he played a misunderstood & underappreciated pantomime horse Artist. Just great!

I'll add myself to the Jeremy Irons followers. His Oscar for Dead Ringers apparently got misplaced (so did Cronenberg's, come to think of it).

Also, to drag in my Fright Night fanboy POV, I must mention Chris Sarandon (husband of Susan) and, of course, Stephen Geoffreys, who was so underrated that he ended up in gay porn. I win.

"Oh, you're SO COOL, BREWSTER!"

Abe Vigoda

Come on it's Abe Vigoda, he's the best.

Martin Sheen isn't underrated, just underused. That may be his choice.

My vote: Terrence Howard. I see his face and sit down to watch whatever he's doing. He's intense, absorbed in his roles and easy on the eyes.
Another: Gary Sinise. Good presence but can't seem to get a movie role unless Tom Hanks is there.

Chris Walken...not many actors could play the exact same character everytime and still get cast in as many movies as he does.
I heart him.
