TVLine Items: House Doc on SVU, Kimmel Assembles Avengers and More

Robert Sean Leonard Law & Order

After handling the irascible House, M.D. for eight seasons, we’re betting Robert Sean Leonard will find Law & Order: SVU perps a cakewalk.

The actor, best known for playing Dr. James Wilson on the medical drama, will appear in a May episode of NBC’s long-running procedural, per The Hollywood Reporter.

In the episode — which will also mark the brief return of Dann Florek’s Capt. Cragen — Leonard will play ADA Kenneth O’Dwyer, who once sent a man to jail for raping his own daughter, but must revisit the case when the daughter recants her testimony.

Since ending an eight-season run on House, Leonard has appeared on The Blacklist, Falling Skies and The Good Wife.
