Rob Morrow stars as FBI agent, Don Eppes who recruits his mathematical genius
brother, Charlie (David Krumholtz), to help the Bureau solve a wide range of
challenging crimes in Los Angeles. Dr. Larry Fleinhardt (Peter MacNicol), Charlie's
friend and colleague, urges him to focus more on his math studies than on FBI
business. A brilliant physicist, Larry is awkward in social situations. (Note: MacNicol

episode, "The Quantum Theory.")

11/28/06: Interview with David Krumholtz at, who talks about the show and working with the
other actors, including Peter: "Peter's really a wonderful guy.... He's never at a loss for something
incredible. He's always offering up some piece of whimsy -- he's quite a character himself. He makes it so
much fun to go to work everyday, to look forward to working with a guy like that, who has sort of a fancy
free attitude about his work. It just makes it so much fun. It becomes like kindergarten. Also, it's highly
efficient. He and I, we just bang it out. We don't waste time. We know what we're there for. The work, or
at least the memorizing of lines, is secondary. The fun that he and I have together is what's primary for
both of us. I'm glad that comes across."

Numb3rs. It has several behind the
scenes photos, Peter is in two of them.

"Solving crime by the Numb3rs":
"MacNicol (
Ally McBeal) was intrigued by the character he was asked to play. 'This character is very
mysterious," he said. 'He's a little bit Yoda, a little bit (physicist) Richard Feynman, a little bit Dr. Watson. It
was probably the third in a series of people (I've portrayed) who I would call a wise fool. It's appealing in
that I don't know what is going on with this character. I don't understand his precise function in the story.'"
