Considering all the crazy film and TV roles he's had over the past year, it is a bit of a surprise to see Matthew McConaughey (mostly) clean-shaven and wearing a suit!

On Wednesday the actor made an appearance on Jimmy Kimmel Live to promote his latest projects (he blew us away in Dallas Buyers Club and he's continuing to do so in HBO's amazing series True Detective), and of course Jimmy brought up the Oscars, which are right around the corner.

Jimmy joked, "We gotta prepare you to win an Academy Award because you know you're going to win, right?" Matty shook his head, but after a brief discussion about True Detective, Jimmy went for it again. "I feel as though you deserve to win the Academy Award, not just because of your performance but also, you starved yourself almost to death ... I feel like just based on that alone you should get it."

The 44-year-old actor laughed and said no, and he added that losing 40 pounds wasn't just to look like the character he was playing, but to understand him. "Doing that for five months put me in a place where I was able to study and surround myself with everything Ron Woodruff, everything about HIV and AIDs at that time -- it was perfect tool -- I didn't even know it would be until I was doing it."

Still, Jimmy wasn't willing to give up about the star taking home the prize for Best Actor, and he asked how the father of three was planning on topping his Golden Globes acceptance speech. "I feel like you wasted your A material on the Golden Globes, and you should've saved it for the Oscars," Jimmy exclaimed. "You have a lot to live up to!" So what does Matty have in mind?
