Lara Jill Miller, Gimme A Break! TV, 1981-1987.   Replaced at the last minute, Tracey became anorexic in the early 1990s; she had to miss most of the seventh and final season of the well-named Growing Pains in 1992. She had her first screen kiss from... Brad Pitt.

Heather Langenkamp, A Nightmare On Elm Street, 1985.   Gold, Demi Moore, Courteney Cox, Jennifer Grey were in the mix for Nancy,  the teenager who utters the immortal cry of horror after a near drowning: "Oh God,  I look 20!" Therefore it took a little longer for Gold  to win (some) glitter, via TV’s Growing Pains, 1989, and a stack of tele-movies.
