This is the Robin Williams picture with him as a clown/doctor:
Fact-based story of Hunter "Patch" Adams (Robin Williams), the founder of the Gesundheit Clinic, a clinic which deals with their patients with humor and pathos. The film starts with Hunter admitting himself as a patient in a mental ward. While there, he found he enjoyed helping the other patients and found the staff to be cold and separative from the patients. Vowing to change things, he releases himself from the hospital and headed to the Virginia Medical College. His unorthodox methods cast him up against many of the doctors and deans of the university, despite him getting some of the highest grades in his class. Recognizing that many poor people were not being treated, as a student he formed the Gesundheit Clinic to aid those who were not getting proper treatment at the hospital. However, this brought him up before the Medical Review Board for practicing without a license.
He also did this, more recent, not quite as healing clown:
Fired in disgrace, kids show host Randolph Smiley finds himself out on the street, while his replacement Sheldon Mopes, finds himself on the fast track to success with a new hit show as the proud purple rhino Smoochy. But things take a turn for the worst when Sheldon finds out that some of the people that he works with, and some he doesn't know he's working for, are all in it for the money. Meanwhile, Randolph is slowly turning insane with his only thoughts focusing on killing Smoochy and getting back to his life of luxury.
This is the movie that was featured at Darren's bad movie party:
Shakes plods about his duties as party clown, and uses all of his free time getting seriously drunk. Binky, another clown, wins the spot on a local kiddie show, which depresses Shakes even more, and his boss threatens him with unemployment if he can't get his act under control. When someone murders Shakes' boss and makes it look like Shakes did it, he goes undercover, posing as a hated mime, and tries to find information that will clear his name.</dt>
