Hal Holbrook, Mark Twain, Scott Teems
Hal Holbrook in character as Mark Twain

AFI Docs will open and close this year's installment of the festival with two quintessential American character studies: "Holbrook/Twain: An American Odyssey" and "Life Itself."

Helmed by "Hoop Dreams" director Steve James, "Life Itself" peers into the life of the beloved late film critic Roger Ebert. "Holbrook/Twain: An American Odyssey," which will have its world premiere at this year's AFI Docs, centers on award-winning actor Hal Holbrook, who, in addition to maintaining a robust career in Hollywood, has been continuously performing his one man show "Mark Twain Tonight!" for the past 60 years.

Holbrook will be in attendance to introduce the film on the opening night of AFI Docs, which will take place on June 18th at the Newseum in Washington, D.C.. "Life Itself" will close out the festival on June 21st at the Smithsonian National Portrait Gallery.
