Presenters for the ceremony include Emily Blunt, Claire Danes, Ralph Fiennes, Katie Holmes, Kristin Scott Thomas, Marisa Tomei, Christina Applegate, Ernest Borgnine, Taye Diggs, Jon Hamm, Anthony Hopkins, John Krasinski, Eric McCormack, Amy Poehler, Susan Sarandon, Kyra Sedgwick, William Shatner and Forest Whitaker.

Tony Award winner James Earl Jones, most recently on Broadway in the revival of Cat on a Hot Tin Roof, will be honored with the 2008 Screen Actors Guild Life Achievement Award during the telecast. The award is given annually to an actor who fosters the "finest ideals of the acting profession." In a previous statement SAG President Alan Rosenberg said, "James Earl Jones' distinguished career on stage, in film, on television, in commercials and as a vocal presence without peer commands our admiration and respect. His long and quiet devotion to advancing literacy, the arts and humanities on a national and local scale deserves our appreciation. It is our honor to bestow the Guild's highest tribute on this extraordinary actor."
