Casting announcements have been trickling in for David Mamet’s new play, Race, arriving at the Ethel Barrymore Theatre this autumn. Film and TV star James Spader (Boston Legal), Kerry Washington (Ray), and Richard Thomas (John Boy on The Waltons) are all set to be in the play, and today it was announced that actor/comedian David Alan Grier will be joining the cast as well. Best known for his comedic work on the ’90s sketch comedy TV show In Living Color, David Alan Grier has been on Broadway several times before, most recently the Broadway revival of A Funny Thing Happened on the Way to the Forum. He made his Broadway debut back in 1981 playing Jackie Robinson in the play The First. Although Race is hotly anticipated, the subject of the piece has remained hush-hush – though most have guessed that it deals with racial relations. Playwright Mamet (Speed-the-Plow, American Buffalo, Glengarry Glen Ross) will direct this production of his own work, marking the first time he has directed a play on Broadway.
