She was a celebrity guest on I'm Telling! (1987) with her older brother, Chuck Zeigler, in 1988.
Heidi Zeigler turned down her offer to take on the role of "Newt" in James Cameron's 1986 box office hit "Aliens" so as to accept her offer to play "Mickey" on "Rags to Riches." Aliens' casting director reported having great difficulty casting Newt; Carrie Henn ultimately landed role, starring alongside Sigourney Weaver and Bill Paxton. Henn received a Saturn Award for best performance by a young actor for her work on Aliens.
