oh that is a mean question! i love all three

I've been a fan of NPH for so many years, nothing's gonna ever change that. I know Nathan Fillion from Buffy but I didn't like him that much, but that's due to his character he played... I'm so looking forward to see the musical! Can't wait til July 15th/17th/19th

I detested Caleb. I couldn't stand the southern accent and he was such an ass but then I watched Firefly and I went "hold on just one tick" as I withdrew my trusty pocketwatch from my vest, "this boy can act, I'll tell you what!" I then fell in love with Nathan and even adore Slither. Following that exclamation I went into my Delorian, clocked up to 88 MPH and returned the pocketwatch and vest.

That's such a tough one. While I do love NPH, I have been drawn to Nathan ever since I saw him on a crappy soap as a wee little girl. He just had that much charisma!

Two words... Doogie Howser.

Two words ... Barney Stinson ;p

^i needed a couple of minutes to get barney oot of my head though..

I agree with nosemuffin. I've loved Nathan Fillion since he played Joey Buchanan on One Life to Live. I just kept following his career. He's great! If anyone hasn't watched the one season of Firefly, I highly recommend it!

I agree with amazondebs.

He was amazing!!

I love NPH but Felicia is such a good actress. Has anyone seen The Guild? She's hilarious in it.

Captain Tightpants.

I didn't pick Simon Helberg, but I'm insulted you left him out haha jk. anyway, NPH all the way!!!!!!!!!

NPH! NPH! NPH! :)

HES SOOO PRETTY!!!!!!!!

First time I saw NPH, been in love with him ever since. And I agree, he's hot!

I love Neil too though. But NF does it for me :) He's my captain :)

Always

Hes Incredible!

Technically Felicia Day is an actress no an actor...but maybe I shouldn't nit-pick as much XD

NPH!! always.

NPH is one of my top two actors. This question wasn't too hard because he was part of it, but if he wasn't then it would have been incredibly difficult to choose.
