Legendary comedian Jerry Lewis makes a rare and dramatic guest star appearance on NBC's Law and Order: SVU as a homeless man who may have a clue to the brutal rape and murder of a mother and daughter. The episode, "Uncle," will air Tuesday, October 10 at 10 p.m. ET/PT.

When a homeless man is found in New York's Central Park and brought in for questioning by Detectives Stabler and Beck, one member of the Unit is dealt an emotional blow as Detective John Munch recognizes the homeless man as his long lost uncle, Andrew. This powerful episode deals with many societal issues including the treatment of the mentally ill and the aged.

Executive Producer Neal Baer commented, "We are thrilled and inspired to be working with Jerry Lewis, a true legend and professional actor. He brings both depth and heart to this role and gives insight into how often older people with depression are misdiagnosed."
