Besides her acting career, Witt was a contestant on a Teen Week edition of Wheel of Fortune in September 1990.
Her roles contain examples of:
- The Cast Show Off: Playing piano on Twin Peaks. (She's a classically trained pianist.)
- Creepy Child: She played Alia Atreides in the 1984 film adaptation of Dune.
- Dull Surprise: Suffered bouts of it in Urban Legend. To be fair, they were asking her to do something she was incapable of, act afraid.
