Kal Penn is such an amazing actor. He has really good versatility because he can do the slacker comedy like Harold and Kumar and at the same time he can pull of dramatic roles like in The Namesake. His big screen roles are really good, but he has had many guest spots on TV as well. He was really good in 24 as the questioning terrorist and it was nice to see him in the very dramatic role.
He is currently on House where his sense of humor comes across really well and his interactions with the rest of the cast are really hilarious.
He is a huge talent and I can't wait to see him in more things and hopefully he'll get his own show.
