Robin Williams has signed on to guest star in the 200th episode of “Law & Order: SVU.”
The actor/comedian will play an engineer whose life has gone off-track following a tragedy. Events lead him to start questioning authority, and encouraging others to do the same.
The episode will air April 29, the first Tuesday of the May sweep.
“SVU” executive producer Neal Baer said the Williams episode boasts a “powerful and complex” storyline. Baer and “SVU” co-executive producer Amanda Green wrote the script.
