"Charlie Brown" actor Peter Robbins gets jail for stalking SAN DIEGO, May 8 (UPI) -- Peter Robbins, the voice of Charlie Brown in "A Charlie Brown Christmas," was sentenced in San Diego to a year in jail for threatening an ex-girlfriend.

He avoided further jail time by participating in an eight-month rehabilitation program, the entertainment news website said. Robbins, who also voiced Charlie Brown in "It's the Great Pumpkin, Charlie Brown," was ordered to stay away from the doctor for 10 years and will be on probation for five years. He also has to pay $15,081.90 in restitution to the ex-girlfriend.
