She rose to stardom with roles in "The Mask" (1994), "My Best Friend's Wedding" (1997), and "There's Something About Mary" (1998), and is also known for voicing the character of Princess Fiona in the "Shrek" series (2001–2010).

In 2001, Cameron voiced Princess Fiona in the movie Shrek, for which she earned $10 million. In the film, her role is plagued by a curse that transforms her into an ogress each and every sunset.

A success with critics, the film also made US $484.4 million at the worldwide box office.
