Tom had several small parts in movies including Nothing Lasts Forever, Wall Street, See No Evil, Hear No Evil, and Blue Steel; but her biggest role to date was as a waitress in the Robin Williams/Tim Robbins film Cadillac Man. This role led to being a guest on The Tonight Show with Johnny Carson. Tom landed a starring role in the film The Joy Luck Club in 1993, which led to roles in such other films such as When a Man Loves a Woman and North.

Since the mid-90s, Tom has starred in few films (focusing her work, primarily, in the voiceover business), with the exceptions of a supporting role in the 2003 hit comedy Bad Santa and the critically-acclaimed 2004 film In Good Company.
