Marcia Clark began practicing law as a criminal defense attorney. She became a prosecutor in the L.A. District Attorney's Office in 1981, and spent ten years in the Special Trials Unit where she handled a number of high profile cases prior to the O.J. Simpson case, including the prosecution of stalker/murderer Robert Bardo, whose conviction for the murder of actress Rebecca Schaeffer resulted in legislation that offered victims better protection from stalkers as well as increased punishment for the offenders.
Since the Simpson trial, Ms. Clark has toured the U.S. and Canada giving lectures on a variety of women's issues including domestic violence and inspirational/motivational speeches, as well as lectures on the latest high profile cases, public service careers, and of course, the Trial of the Century.
In May of 1997, her book on the Simpson case, Without a Doubt was published and quickly rose to #1 on the New York Times, Wall St. Journal, Washington Post, LA Times, and Publisher's Weekly bestsellers lists.
From February 1998 to 2000 Marcia was under contract as a legal analyst and expert commentator for NBC, CNBC and MSNBC. She appeared weekly as the substitute host of Geraldo Rivera's Rivera Live, and also hosted Equal Time for CNBC and Judge and Jury for MSNBC. Marcia has appeared on the Oprah Winfrey Show, the Larry King Show, the Today show, The Early Show, and Good Morning America, among others, and provides legal commentary on a wide variety of cable shows such as Anderson Cooper 360 and Issues with Jane Velez Mitchell.
Marcia Clark (with writing partner, Catherine LePard) has sold hour-long pilots to the FX network, Lifetime, and VH1 and developed a half hour comedy for NBC. She has also developed reality projects for CBS and was an executive producer of a one hour reality pilot for CBS.
