Caitlin McKenna-Wilkinson, C.S.A., was Lost's ADR voice casting casting director. "ADR" is an industry abbreviation for "additional dialog recording". As such, she was likely responsible for casting:
- India Dupre to replace the voice of Jenny Chang for the character Rachel
- Valerie McTavish's voice in the tape recording of Charlotte Malkin's aborted autopsy
- Lynnanne Zager as the computer's voice in the Swan and Hydra stations
- Skye McCole Bartusiak and Carter Jenkins as the voices of the young Kate and Tom Brennan in the time capsule tape
- The newsreader of "The Beginning of the End"
- The unknown actors in "Confirmed Dead" for the female and male Oceanic hotline operators, and the two ROV operators Ron, and another unnamed one.
McKenna-Wilkinson has also worked as ADR voice casting in many productions including The Bourne Ultimatum, I am Legend, Body of Lies, Star Trek (2009), and Watchmen, and as a voice actor in the 2006 film A Good Year.
