Krakowski made her movie debut in "National Lampoon's Vacation"; she has also appeared in "Fatal Attraction", "The Flintstones in Viva Rock Vegas" (where she played Betty Rubble), "Marci X", "Alfie", "Go", "", "Dance with Me", "Stepping Out", "Pretty Persuasion", "", and "Mom at Sixteen". Krakowski was originally cast in the horror movie "Sleepaway Camp", but dropped out just before filming began because she felt her character's death scene with a curling iron was so violent. She appeared in "When Zachary Beaver Came to Town" as a mother who wants to become a singer. In 2004, she starred in Alan Menken's TV movie version of "A Christmas Carol", featured as "The Ghost of Christmas Past".
