Variety is reporting that Saturday Night Live's Cheri Oteri — best known for her impersonations of Barbara Walters, Judge Judy and Melissa Rivers — is quitting the sketch show to pursue a career in prime time and films. The comedian — arguably one of the best things about SNL in recent years — has enjoyed great success this summer, starring in the sleeper hit Scary Movie and earning an Emmy nomination for her guest stint on NBC's Just Shoot Me. According to the trade paper, the networks have approached Oteri about a sitcom deal. An SNL rep had no comment at press time.
