Robin Williams is getting the "especially heinous" ripped-from-the-headlines treatment.

The Oscar winner is set to guest star on the 200th episode of Law & Order: SVU, playing an engineer who, having suffered through a life-changing tragedy, has developed a deep distrust of authority and feels compelled to inform others about the dangers in "leading unquestioning lives," per NBC.

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