Known for her supporting roles, Kim Walker was an up and coming young actress in Hollywood before retiring from the business in the late 1990s. As a teen she landed a few guest roles in series such as Matlock and Highway to Heaven before moving on to supporting roles in feature films such as Say Anything... and several made-for-television films. However, Kim Walker will forever be remembered for her role as Heather Chandler in the now cult-classic Heathers which starred a young Winona Ryder in her first starring role. The role, which had Kim playing possibly the nastiest, most difficult teenager in the history of film won her acclaim and a legion of fans due to her legendary lines and her on-screen persona in this black comedy about high school life. With such lines as "You're such a pillowcase!", and "Did you eat a brain tumor for breakfast?", Walker was a scene stealer during the early-half of the film.
Attended the famous High School of Performing Arts in New York City. Buried in Pinelawn memorial park, in Farmingdale, New York.
