Actors Who Appeared On Law & Order Before They Were Stars

Allison Janney Made Two Appearances On L&O Before Landing Her Gig On West Wing

Many people know who actress Allison Janney is. Her acting resume is quite large. But like everyone else she had to start somewhere, and for her, that was a small role in a 1992 episode of the show. The episode revolved around the murder of a soap star. She returned two years later and played a witness against the Russian mob. Just five years later she landed one of her most famous parts: the role of C. J. Cregg on the NBC drama The West Wing. These days she stars on Mom alongside Anna Faris. She also made a splash in the Tonya Harding biopic I, Tonya.
