Williams is just what NBC ordered


Robin Williams will make a rare TV appearance on NBC's crime drama "Law & Order: SVU."

On the series' 200th episode, slated to air April 29, he will play a law-abiding engineer whose life takes a tragic turn, and he becomes an ardent believer in the necessity of challenging authority.

"We are thrilled that one of the most talented and versatile actors around will be starring in this powerful and complex special 200th episode," "SVU" executive producer Neal Baer said. "We can't imagine anyone else doing this role."
