Richard is a SAG member and thinks that Letterman is a “pig” for going back to work, even after carving out a deal with the WGA.

As he told me, he "starred" in the Billy Crystal/Robert De Niro movie "Anaylze This." Here’s his official Web site

Some guy from Letterman called the cops on him and the police officer made him go up the block a bit.

Vidiot pointed out in my Flickr comments that he was once profiled on This American Life.

“Act One. Self-Deception. This American Life producer Alex Blumberg tells the story of an ex-con-turned-actor named Richie Castellano. After a bit role in the movie Analyze This, he moved to a small town and got dozens of people to invest money and time in a movie that never premiered. Why so many people bought into his grandiose dreams, and what they learned about him—and themselves—after they got burned for it.”
