The veteran actor takes on the role of the famed investor in new HBO film Too Big To Fail alongside co-stars James Woods and William Hurt.
The Mary Tyler Moore Show star thoroughly researched the role, but never had the opportunity to come face-to-face with Buffett.
He tells Cindy Adams of the New York Post, "I'd like to meet Buffett, but I'm not the sort to reach out. I don't do those things. Not that type. I handle things sedately."
Too Big To Fail is due to air in the U.S. on 16 May (11).
