Robert Downey, Jr. — who just signed on to do eight more episodes of Fox's Ally McBeal — will introduce a special salute to "Actors of 1000 Faces" at the 7th Annual Screen Actors Guild Awards, airing March 11 on TNT (8 pm/ET). Downey is up for best supporting actor for his Ally McBeal work. Meanwhile, the actor's next court hearing, scheduled for Wednesday, is expected to be postponed so lab tests can be completed. Downey faces drug charges stemming from his Thanksgiving weekend arrest in Palm Springs.
